feat(desktop): system tray + minimize-to-tray (T2)

[qnbs]

User description

Phase T2 — System tray

Stacked on T1 (#189). Native-desktop plan, Core+power. CodeAnt review deferred to the combined final pass.

What

• Real system tray (the prior "tray service" was only a window show/hide helper). Built in JS via @tauri-apps/api/tray, localized (ADR-D1): icon + tooltip, context menu (Show / Settings / Command Palette / Quit), left-click focuses the window. isTauriRuntime()-gated → no-op on web; created once per session.
• Minimize-to-tray: installCloseToTray(getter) hides instead of quitting when enabled (reads the setting live). New desktop settings group (minimizeToTray, default off) — type + slice default + setDesktopSettings + normalizePersistedSettings backfill; DesktopSection toggle in Settings → About (desktop-only).
• i18n desktop.tray.* + desktop.settings.* across all 17 locales (5 core translated); bundles rebuilt, parity green.
• Rust: tauri = { features = ["tray-icon"] } + tray/window capabilities.

Tests / gates

• desktopTray (7) + settingsSlice desktop default/setter (2) + fixed the languageToolClient full-Settings mock. typecheck/lint/token-audit (160≤165)/i18n:check green.
• Rust verified via tauri-build.yml dispatch (no PR gate). Tray capability/runtime behavior is confirmed on a real desktop (can't run a Tauri shell on the CI/dev host).

CodeAnt-AI Description

Add a system tray and an optional close-to-tray setting for the desktop app

What Changed

• The desktop app now shows a system tray icon with actions to reopen the app, open Settings, open the Command Palette, or quit
• Clicking the tray icon brings the window back to the front
• A new desktop setting lets users keep the app running in the tray when they close the window instead of quitting
• Existing saved settings now fill in the new desktop option and treat invalid values as off, so close-to-tray works consistently

Impact

✅ Fewer accidental quits on desktop
✅ Faster reopen from the tray
✅ Clearer desktop controls for Tauri users
