chore(packaging): add AUR package sources for source, git, and binary builds

packaging/aur/ now holds the full content of three AUR repositories:
proton-drive-for-linux builds the latest tag from source,
proton-drive-for-linux-git builds main, and proton-drive-for-linux-bin
installs the binaries attached to the GitHub release. Each carries a
PKGBUILD, a generated .SRCINFO, an ignore-everything .gitignore, and the
0BSD license the AUR expects for package sources.

update.sh bumps the release-based packages and regenerates the .SRCINFO
files; push.sh publishes each package to its AUR remote. The README now
points users at the AUR packages and keeps the in-tree PKGBUILD as the
development build.

+| Package | Contents |
+| --- | --- |
+| [`proton-drive-for-linux`](https://aur.archlinux.org/packages/proton-drive-for-linux) | builds the latest tagged release from source |
+| [`proton-drive-for-linux-git`](https://aur.archlinux.org/packages/proton-drive-for-linux-git) | builds `main` from git |

+The package sources live in `packaging/aur/`; see
+[`packaging/aur/README.md`](packaging/aur/README.md) for how they are updated and
+published. A local `PKGBUILD` that compiles the working tree in place is still
+available for development builds:

 cd packaging && makepkg -fi

+# AUR packages
+
+Source of truth for the three AUR packages of this project. Each subdirectory is
+the full content of one AUR git repository (`pkgbase` = directory name):
+
+| Directory | What it does | AUR repository |
+| --- | --- | --- |
+| `proton-drive-for-linux` | Builds the latest tagged release from source | `ssh://aur@aur.archlinux.org/proton-drive-for-linux.git` |
+| `proton-drive-for-linux-git` | Builds `main` from git | `ssh://aur@aur.archlinux.org/proton-drive-for-linux-git.git` |
+| `proton-drive-for-linux-bin` | Installs the binaries from the GitHub release | `ssh://aur@aur.archlinux.org/proton-drive-for-linux-bin.git` |
+
+The three packages conflict with each other and with the in-tree
+`packaging/PKGBUILD` package (`proton-drive-linux`), and every one of them
+`provides` `proton-drive-for-linux`, `proton-drive-linux`, and `pdfs`.
+
+Each directory tracks only `PKGBUILD`, `.SRCINFO`, `.gitignore`, and `LICENSE`
+(the 0BSD license of the packaging sources, per
+[RFC40](https://rfc.archlinux.page/0040-license-package-sources/)); the
+`.gitignore` ignores everything else so downloaded sources, `src/`, `pkg/`, and
+built packages never reach the AUR.
+
+## Releasing a new version
+
+1. Tag and publish the upstream release, so the source tarball and the
+   `proton-drive-linux-<version>-x86_64.tar.gz` release asset exist.
+2. Run `./update.sh <version>` — it rewrites `pkgver`, resets `pkgrel=1`,
+   refreshes the checksums of the release-based packages, and regenerates every
+   `.SRCINFO`.
+3. Build and inspect the packages in a clean chroot:
+   `cd proton-drive-for-linux && pkgctl build --clean` (needs `devtools`).
+4. Commit here, then publish with `./push.sh` (or `./push.sh proton-drive-for-linux-bin`
+   for a single package).
+
+`proton-drive-for-linux-git` carries a `pkgver()` function, so its `pkgver` is
+computed at build time; do not push a commit that only bumps it.
+
+## Requirements for pushing
+
+An SSH key registered with the AUR account and an entry in `~/.ssh/config`:
+
+```
+Host aur.archlinux.org
+  IdentityFile ~/.ssh/aur
+  User aur
+```
+
+`push.sh` creates a scratch clone of the AUR repository, copies the tracked
+files over it, commits, and pushes to `master`.
