feat(dashboard): auto-update with Tauri updater plugin

- Added tauri-plugin-updater, plugin-process, plugin-dialog (Rust + npm)
- Generated signing keypair (private key gitignored, pubkey tracked)
- Configured updater endpoint to GitHub releases latest.json
- Added capabilities/default.json with updater, dialog, process perms
- Created updater.ts with check → download → install → relaunch flow
- App.tsx polls for updates on mount then every 10 minutes
- Shows persistent toast banner with 'Install & Restart' / 'Later' actions
- Added dashboard-release.yml CI workflow for cross-platform builds
  with tauri-action generating signed updater artifacts
- Requires TAURI_SIGNING_PRIVATE_KEY secret in GitHub repo settings
