v0.3.1 — view-panel tabs, tray + notifications, server-activity, media preview, dockable locks

- Tabbed view panel: File Viewer / File Tree / File Locks, header hidden at one tab, re-openable from Window, state persisted
- Right-click Workspace/Working-folder zones -> Show in File Tree (focuses the right side)
- Commit weight shown in History (p4 sizes -s //...@=CH)
- Rich code editor (highlighted underlay + gutter) and clean spec-editor surfaces (no more grey notepad)
- System tray (close-to-tray, tray menu Quit) + native OS notifications for teammate submits, even when hidden
- 'You're behind the server' banner + native notification (p4 sync -n), rechecked only when the server advances
- Audio & video preview with playback (media-src blob CSP); File Locks dockable into the view panel
- Backend: depot_ls/fs_ls, p4_change_sizes, p4_behind; tauri-plugin-notification + tray-icon
