westerm v0.3.0

Added

• Desktop app for Windows and Linux, from the same code as the macOS app (Tauri 2, in desktop/). Windows: westerm-windows-app-setup.exe. Linux: .deb and .rpm for x64 and arm64. Like the macOS app, it opens the westerm on port 4317 or starts the one it ships, and quitting it keeps your shells running. A second launch brings the open window forward. On Linux an update opens the release page; install the new package from there.
• Docs pane: a new pane that lists a folder's Markdown files as a tree and shows them in View, Edit, or Split mode. It opens in the focused shell's folder and can follow that shell's cd. ⌘S saves; a file changed on disk since editing started asks before it is overwritten. Unsaved changes are kept per file across reloads. In a remote window it shows the server's files.
• AI agents in shells: while Claude Code or Codex runs, the pane header and the sidebar show an AI mark with a ring for its state (working, needs input, done out of view, idle), and the tab shows a dot. macOS and Linux.
• A shell that comes back as "restored" (a reboot, a logout, westerm stop, a host update) resumes the agent it ran: claude --resume <id> with the flags it had, or codex resume --last. Settings ▸ Terminal ▸ Resume AI agents turns it off.
• The AI mark in a pane header opens the agent's card: its state and for how long, the conversation id, the folder, the model, the command a reboot runs (with Copy buttons), and a choice to keep this pane from resuming.

Changed

• The macOS app is now the same Tauri app as on Windows and Linux; the Swift app (macos/) is gone. It keeps the window, the remote windows, the menu, and the update from westerm-macos-app.zip, so the old app updates to it as before. Its log moves to ~/Library/Logs/io.github.steelcrab.westerm/westerm.log. Check for Updates now opens the dashboard's update panel.
• GET /api/update reports the channel app instead of mac-app for a westerm inside the desktop app.
• ⌘ terminal keys (⌘1–9, ⌘] and so on) work in the macOS app only. On Windows and Linux the app uses the Ctrl+Shift keys.
• terminal-browser and terminal-code panes are much faster. The PTY host now takes their pictures through shared memory instead of base64 text, keeps them, and sends the page only the changed rectangles, which a Worker draws off the main thread. In a 1700 × 1000 pane, scrolling went from 8 to 107 frames a second and video from 5 to 107, and the page's main thread no longer stalls (long tasks: 160–220 ms a second → 0). A remote window gets the rectangles compressed. Set localStorage["westerm.pixels"] = "off" in the page to get the old way back. This changes the PTY host, so shells restart once when this version starts (their screens are restored).

Fixed

• A Kitty image that changes no longer makes wterm repaint every other image on screen. In a terminal-browser pane on the old path, a blinking caret repainted 1.8 million pixels; now it repaints the 40 that changed.
