chore(version) bumped to 1.10.0

- A queued rename that also changes folder now lands as one `move-multiple`
  request carrying the target name instead of rename-then-move, so there is
  no half-applied state and no second call for stale name requirements to
  hit (B46 follow-up). A destination name collision moves under a conflict
  name in one step; same-folder renames still use the rename endpoint.
- Shared with me shows the inviter and invite date (GUI subtitle, `pdfs
  shared-with-me`), with a warning when the invitation signature does not
  verify against the claimed inviter's keys. `DirEntry` gains `shared_by`,
  `shared_at` and `shared_by_unverified`, all serde-defaulted.
- Bump `proton-sdk` / `proton-drive-rs` to 0.6.3 (anonymous-node moves,
  `TrashTime` trashed detection).

+
+One-request move-and-rename in the drain, and who shared an item with you. No schema change.
+Schema: **28**; SDK bumped to `proton-sdk` / `proton-drive-rs` **0.6.3**.
+
+### Added
+- **Shared with me says who shared an item, and when.** The GUI row subtitle and `pdfs
+  shared-with-me` show the inviter and invite date for a share root. The invitation's signature is
+  checked against the claimed inviter's keys; when it does not verify, the GUI shows a warning
+  and the CLI prints one, since the sender may be forged. `DirEntry` gains `shared_by`,
+  `shared_at` and `shared_by_unverified` (defaulted, so older front-ends and daemons interoperate).
+
+### Changed
+- **A queued move-and-rename lands as one request.** `drain_rename` used to rename in the source
+  folder and then move, with a rename-out-of-the-way step when the destination held the name. It
+  now calls `move-multiple` with a target name, so there is no half-applied state between the two
+  halves and no second call for the encrypted-name requirements to go stale against (B46). A
+  rename that stays in the same folder still uses the rename endpoint.
+
+### Fixed
+- **Moving a node with no signature email no longer fails.** Such nodes (created anonymously, e.g.
+  through a public link) need the passphrase signed by the mover; SDK 0.6.3 sends that signature.
+- **A node trashed through the newer API field is recognised as trashed.** The SDK now reads
+  `TrashTime` as well as the legacy `Trashed` field, so the drain no longer tries to rename a node
+  that is already in the trash.
+
+## [1.9.3] — 2026-09-01
+
+The daemon's wait-for-login loop, and the latency that fixing it introduced. No schema change.
+Schema: **28**; SDK unchanged at `proton-sdk` / `proton-drive-rs` **0.6.2**.
+
+### Fixed
+- **An enabled service with no saved session no longer polls the keyring 28,800 times a day.**
+  `wait_for_session` slept a flat 3 s between checks, and a check is not just a sleep — `auth::load`
+  builds a fresh `keyring::Entry`, so every iteration opened a new D-Bus connection to the Secret
+  Service and negotiated a session on it. The wait now backs off, and "not logged in" is said once
+  at `info` instead of on every pass, which also stops the journal filling with tens of thousands
+  of identical lines (`#21`).
+- **Signing in wakes the parked daemon instead of leaving the mount up to an interval late.** The
+  backoff had no wake-up path: a unit started at boot reaches the ceiling within ~90 s, and
+  `enable --now` is a no-op on an already-active unit, so the GUI login and the tray's Connect left
+  it sleeping. `service::enable_start` now runs `enable` + `restart`, which interrupts the sleep and
+  still starts a unit that is down, and `pdfs login` restarts the unit when it is already active —
+  deliberately without touching `enable`, so a headless setup driving `pdfs daemon` by hand is left
+  alone. The ceiling also drops from 60 s to 15 s, still an 80% cut in keyring/D-Bus wakeups
+  (28,800/day → 5,760/day), bounding the worst case for paths that never reach systemd.
+
+### Changed
+- The wait is extracted into `wait_for_session()`, taking the load and sleep calls as parameters,
+  so the schedule is testable without a keyring and without real time passing.
