feat(app): add Settings view, configurable claude dir, and recap docs refactor

Introduce a Settings view for configuring the Claude data directory
  (with WSL auto-detection on Windows), sidebar project grouping module,
  and an empty-state onboarding screen for SessionList. Refactor
  recap-patterns.md into per-card reference files under references/recap/
  with separate retrieval and writing guides. Remove the legacy panel.html.
  On the data layer: incremental indexing via changedPaths, per-session
  live-update IPC (obelisk:session-updated), and session dirty-tracking
  in the renderer.
