Startup sequence now:
1. Creates data directories (~/.local/share/mc/)
2. Cleans up orphaned tmp files from crashes
3. Verifies CLI dependencies (lore, br, bv) asynchronously
4. Emits startup-warnings event with missing CLI warnings
5. Emits cli-availability event with tool status
6. Emits startup-sync-ready when CLIs available
This enables the frontend to:
- Display warnings for missing tools
- Know which features are available
- Trigger reconciliation when ready
