- Set JOURNAL_PROJECT_ROOT and CWD when spawning sidecar so data
lands at repo root instead of under src-tauri/ (fixes dev watcher
hot-reload loop triggered by schema file writes)
- Add backend client layer (auth.ts, client.ts, fragments.ts, types.ts)
- Wire vault unlock flow with password prompt modal on locked DB
- Update fragments store with full sidecar CRUD integration
- Update EditorPanel and AppModal for fragment editing support
- Gitignore runtime journal/ and logs/ directories
