chore(release): 2.3.0

The Places view gets a Grid/Map toggle. The map shows a bubble per town,
sized by its number of photos, over the outline of the world's land. Towns
whose bubbles would overlap merge into one that counts all their photos, and
clicking it zooms in until they part; clicking a single town opens it like a
card does. Drag to pan, scroll or pinch to zoom, and the buttons zoom in,
zoom out or frame every place again. Hovering names the town, or the first
few towns of a merged bubble.

No tile server is involved: none that is free has terms allowing an app like
this one to use it. The map is drawn from Natural Earth's 1:50m land
polygons (public domain), trimmed and simplified by
scripts/natural-earth-land.py into crates/pdfs-gui/data/land.txt, in Web
Mercator. The About dialog credits Natural Earth.

PlaceInfo carries the town's latitude and longitude; a daemon older than the
map sends none, and its towns are left off the map.

+# Code of Conduct
+
+## Our pledge
+
+We want participation in this project to be a harassment-free experience for everyone, regardless
+of age, body size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socioeconomic status, nationality, personal appearance, race,
+religion, or sexual identity and orientation.
+
+## Standards
+
+Examples of behavior that helps:
+
+- being respectful of differing viewpoints and experience levels,
+- giving and accepting constructive feedback gracefully,
+- focusing on what is best for the project and its users.
+
+Examples of unacceptable behavior:
+
+- sexualized language or imagery, and unwelcome sexual attention,
+- trolling, insulting or derogatory comments, and personal or political attacks,
+- public or private harassment,
+- publishing others' private information without explicit permission.
+
+## Scope and enforcement
+
+This applies in all project spaces — issues, pull requests, discussions — and when representing the
+project in public. Report unacceptable behavior to <contact@narl.io>. Reports are handled
+confidentially. Maintainers may edit, remove, or reject contributions that violate this document,
+and may temporarily or permanently ban any contributor for behavior they deem inappropriate.

+# Contributing
+
+Thanks for taking the time. This is an unofficial Proton Drive client that people trust with real
+files, so the bar for changes that touch the filesystem, the sync engine, or the database is
+deliberately high — everything else is ordinary Rust review.
+
+## Before you start
+
+- Read [`AGENTS.md`](AGENTS.md) for repository conventions and
+  [`docs/ARCHITECTURE.md`](docs/ARCHITECTURE.md) for how the daemon, front ends, and SDK fit
+  together.
+- Check [`docs/BUGS.md`](docs/BUGS.md) — it is the authoritative issue ledger, and your problem may
+  already be tracked there with context.
+- For anything larger than a fix, open an issue first so the design can be discussed before you
+  spend the time.
+
+## Development setup
+
+```bash
+git clone https://github.com/narrrl/proton-drive-linux.git
+cd proton-drive-linux
+cargo build --workspace
+```
+
+GUI and FUSE targets need the GTK4, libadwaita, WebKitGTK 6, libsecret, D-Bus, and FUSE3
+development packages listed in the [README](README.md#prerequisites). Minimum supported Rust
+version is 1.96.
+
+## Quality gates
+
+CI runs exactly these, and they must pass with zero warnings:
+
+```bash
+cargo fmt --all -- --check
+cargo clippy --workspace --all-targets -- -D warnings
+cargo test --workspace --locked
+scripts/fuse-acceptance.sh --offline-only
+```
+
+Changes to the FUSE layer, sync, or the pending-operation queue should also be exercised against a
+real mount before review — see [`docs/TESTING.md`](docs/TESTING.md). Live runs are destructive:
+use a dedicated test account, never one holding data you cannot lose.
+
+## Making changes
+
+- **Keep shared logic in `pdfs-core`.** The CLI and GUI never touch the database or the network;
+  they speak the control protocol to the daemon.
+- **The SQLite schema is forward-only.** Never edit a shipped migration — add a new one and bump
+  `SCHEMA_VERSION` in `crates/pdfs-core/src/db/migrations.rs`.
+- **Typed errors and `?` over panics** on runtime paths. Blocking filesystem, keyring, or
+  control-socket work stays off GTK's main thread.
+- **`staging/` and `recovery/` may hold the only copy of user data.** Nothing may clear or purge
+  them opportunistically.
+
+## Commits and pull requests
+
+Commits follow scoped [Conventional Commits](https://www.conventionalcommits.org), e.g.
+`fix(fuse,core): keep truncate composable with queued revisions`.
+
+A pull request should state:
+
+- the user-visible effect and which crates it touches,
+- the `docs/BUGS.md` entries it fixes or affects,
+- the commands you ran to verify it,
+- screenshots for GTK changes,
+- and, explicitly, any migration, recovery, data-loss, or packaging implications.
+
+## Security
+
+Do not open a public issue for a vulnerability — see [SECURITY.md](SECURITY.md).

 ## Features
 
 - **Files-on-Demand (FUSE)**: Mount your Proton Drive as a virtual filesystem where files are downloaded only when opened, utilizing smart block-level caching and disk-backed writes.
 - **Command-Line Interface (CLI)**: Manage your drive, authenticate, and monitor sync status directly from the terminal.
 - **Non-Blocking GTK4 Desktop App**: Browse files, manage pins, configure options, and monitor active transfers through a modern, native GUI with a fully non-blocking asynchronous main loop.
+- **File Thumbnails**: Browse locally cached image previews in Files, Shared, and Trash, including embedded previews from camera RAW files. Build a whole folder tree from the Files toolbar and resize the grid from the status bar.
 - **Shared Links & Invites**: Browse files shared with you by other users, and view/manage your own public shared links directly in the GUI.
 - **Local Backup (Computers)**: Sync and back up local directories (like Downloads, Documents, Pictures, etc.) directly to your Proton Drive account.
 - **Locations**: One page (and `pdfs locations`) listing every place Proton Drive occupies on this machine — the main mount plus each backed-up folder — with its mode, sync state, and whether it is read-only. Switching a folder between a full local copy and on-demand happens here.
 - **System Tray Integration**: Background indicator for status monitoring, quick actions, and fast sync controls.
-- **Unified Search Launcher (HUD)**: A resident Google Drive-style launcher (`pdfs-prompt`) that searches Proton Drive and local files together, ranks the best matches, tolerates abbreviations and typos, and is ideal for a system-wide hotkey.
+- **Unified Search Launcher (HUD)**: A resident Google Drive-style launcher (`pdfs-prompt`) that searches Proton Drive and local files together, ranks the best matches, tolerates abbreviations and typos, and is ideal for a system-wide hotkey. It can also present the same search in your own launcher (`--dmenu`) or, searching live as you type, in `fzf` (`--fzf`).
 - **Secure Credential Storage**: Integrates with the system Secret Service (GNOME Keyring, KWallet, etc.) with smart in-memory credential caching to avoid UI thread blockages.
 - **Proton Photos Support**: Access your Proton Photos timeline, view thumbnails, and download backed-up media natively (available in the GUI as a navigation tab and via the CLI).
 - **File Version History**: Every revision Proton Drive still holds for a file, from the browser's details pane (**Versions**) or `pdfs versions list|restore|save|rm`. Restoring is server-side — no re-upload — and an old version can be written out to a local file without touching the live one.
 - **Photo Favourites**: Star a photo in the lightbox, filter the gallery to favourites, or use `pdfs favorite <uid>` / `pdfs photos --favorites`.
 - **Photo Albums**: Browse your albums — including the ones shared with you — from the Albums view of the Photos page, or with `pdfs albums` / `pdfs album <uid>`. Album contents open in the same gallery as the timeline.
+- **Places**: The Places view of the Photos page groups photos by the town they were taken in, using the location stored with each photo, as cards or on a world map. Towns are looked up offline in [GeoNames](https://www.geonames.org/) data (CC BY 4.0), and the map is drawn offline from [Natural Earth](https://www.naturalearthdata.com/) land outlines (public domain), so no map tiles are fetched; install `iso-codes` for country names in your language.
 - **Human Verification (CAPTCHA) Recovery**: Detects sign-in gates (VPN/new IP challenges) and launches an embedded `WebKitWebView` dialog to safely complete the challenge, transparently retrying authentication with the earned token.
 - **Selective Sync (`.pdfsignore`)**: Keep build trees, dependency directories, and editor leftovers out of synced folders using gitignore-style rules.
 - **Data-Safe Offline Writes**: Durable scratch/staging files and a transactional pending queue preserve acknowledged writes across network failures and restarts.

 anywhere in `menu` is replaced by the prompt text; without one, the launcher's
 own prompt flag is appended.
 
+### Live launcher search (fzf)
+
+The two-step above exists because no dmenu-style launcher can call back for new
+results per keystroke. `fzf` can, so `pdfs-prompt --fzf` searches as you type,
+exactly like the built-in window:
+
+```bash
+pdfs-prompt --fzf                    # pinned files, then live results as you type
+pdfs-prompt --fzf --query invoice    # start on a search
+```
+
+Every keystroke re-queries the daemon (debounced, like the GTK prompt) and fzf's
+own matcher is switched off, so the ordering you see is the daemon's ranking —
+abbreviations and typos included, which a launcher filtering a fixed list cannot
+do. Enter opens; Escape closes.
+
+fzf is a terminal program, so when it is started without one — from a WM
+keybinding — it spawns a terminal for itself: foot, ghostty, kitty, alacritty,
+wezterm or xterm, whichever is installed. Each is launched with the app-id/class
+`pdfs-prompt`, so one window rule floats it whichever terminal you have. In
+Hyprland:
+
+```
+windowrulev2 = float, class:^(pdfs-prompt)$
+windowrulev2 = size 900 500, class:^(pdfs-prompt)$
+windowrulev2 = center, class:^(pdfs-prompt)$
+bind = SUPER, space, exec, pdfs-prompt --fzf
+```
+
+Set it as the default front end, and pick the terminal explicitly, in
+`config.json`:
+
+```json
+{
+  "prompt": {
+    "mode": "fzf",
+    "terminal": ["foot", "--app-id=pdfs-prompt", "--"],
+    "menu_limit": 50
+  }
+}
+```
+
+A `{cmd}` token anywhere in `terminal` is replaced by the command to run;
+without one it is appended, which is what every detected terminal expects.

+
+## Supported versions
+
+Fixes land on the latest release. Please reproduce on the most recent version before reporting.
+
+## Reporting a vulnerability
+
+**Do not open a public issue.** Report privately through GitHub's
+[private vulnerability reporting](https://github.com/narrrl/proton-drive-linux/security/advisories/new),
+or by email to <contact@narl.io>.
+
+Please include the version (`pdfs --version`), your distribution and desktop environment, what an
+attacker gains, and a reproduction if you have one. You can expect an acknowledgement within a few
+days; a fix ships in the next release, and you are credited in the advisory unless you ask
+otherwise.
+
+## Scope
+
+This client holds Proton account credentials and decrypted file content on the local machine, so
+the interesting boundaries are:
+
+- **Credentials.** Sessions and the mailbox password live in the system Secret Service. Anything
+  that writes them elsewhere — logs, temp files, crash dumps — is a vulnerability.
+- **The control socket.** Anything that can connect to `control.sock` has the daemon's
+  authenticated session. It is `0600`, and the state, cache, and config directories must be real,
+  current-user-owned `0700` directories; the daemon fails closed otherwise. Reports that defeat
+  those checks are in scope.
+- **Local cache and staging.** Decrypted block content and staged writes on disk.
+- **Cryptography.** Key derivation, signature handling, and anything that could publish plaintext
+  or the wrong key material to Proton.
+
+Out of scope: vulnerabilities in Proton's own service (report those to Proton AG), and issues that
+require an attacker who already has your user account on the machine.

+/// on-demand mount is irreversible in practice: the only exit is a rename to a
+/// finished name, and a file that is simply *called* `index.tmp` — a static-site
+/// template, a tool's output — never gets one. It then never reaches Drive at
+/// all, silently, while its bytes pin `staging/`. That is what a real Takeout
+/// tree of `index.tmp`/`preview.tmp` gallery templates did: 43 creates parked
+/// forever. The generic-scratch case they were added for renames within
+/// milliseconds, so it never needed the park; the download suffixes below, which

+//! Listing and resolving `(sync-conflict …)` copies for the user.
+//!
+//! The sweep ([`crate::sweep`]) removes copies it can prove identical and flags
+//! the rest once in the activity feed. That leaves divergent copies sitting in
+//! folders with nothing but a name to find them by. This module lists them with
+//! the file they are a copy of, and resolves one the way the user chooses:
+//!
+//! - **Keep the original**: trash the copy.
+//! - **Keep the copy**: trash the original, then give the copy its name.
+//! - **Keep both**: rename the copy to a name of the user's choosing.
+//!
+//! Every resolution goes through the Proton trash, never a delete, so a wrong
+//! choice is undone by restoring from Trash. Resolution refuses to touch a file
+//! that is open, being written, or still owed an upload, for the same reason the
+//! sweep does: the node is about to change under the decision.
+//!
+//! Copies under My Files are named by their mountpoint-relative path. Copies
+//! inside a synced folder are named by their absolute local path, so a resolve
+//! request routes to the on-demand mount that serves them. A copy inside a
+//! mirror folder is listed too, but it is a local file first: the sync engine
+//! owns it, so it is resolved by editing the folder, not through here.

+//! Pausing sync: the user's "stop uploading for a while".
+//!
+//! A pause holds back the two things that push local state to the remote — the
+//! drain worker's queued uploads and changes, and the mirror-folder reconcile.
+//! Nothing else stops: reads through the mount keep hydrating on demand (a read
+//! is not a sync), writes keep being accepted and staged, and the watcher and
+//! poll keep noticing changes. Resuming lets all of it catch up at once.
+//!
+//! The pause is persisted in the database, so a restart does not quietly undo
+//! it. A timed pause ends by itself; [`Core::set_sync_paused`] arms a timer for
+//! that, and [`Core::sync_paused`] compares against the clock anyway, so a
+//! deadline that passed while the daemon was down is already over on mount.
+//!
+//! A single mirror folder can be paused on its own as well: its reconcile is
+//! skipped, and with it any mode switch queued behind that reconcile, until the
+//! folder is resumed. On-demand folders cannot be paused alone — their writes
+//! go through the shared queue, which only the global pause holds back.
