feat(tauri): kryton:// deep link handling

- add tauri-plugin-deep-link crate (already added to Cargo.toml in prior commit)
- register kryton:// scheme in tauri.conf.json plugins.deep-link.desktop.schemes
- add global-shortcut and deep-link permissions to capabilities/default.json
- add fs:allow-read-file for drag-drop binary reads
- add src/tauri/deep-link-bridge.ts: parseDeepLink() handles note, daily,
  search, settings URLs; setupDeepLinks() opens target account window then
  calls onUrl callback
