feat(electrobun): final 5% — full integration, real data, polish

1. Claude CLI: additionalDirectories + worktreeName passthrough
2. Agent-store: reads settings (default_cwd, provider model, permission)
3. Project hydration: SQLite replaces hardcoded PROJECTS, add/remove UI
4. Group hydration: SQLite groups, add/delete in sidebar
5. Terminal auto-spawn: reads default_cwd from settings
6. Context tab: real tokens from agent-store, file refs, turn count
7. Memory tab: Memora DB integration (read-only, graceful if missing)
8. Docs tab: markdown viewer (files.list + files.read + inline renderer)
9. SSH tab: CRUD connections, spawn PTY with ssh command
10. Error handling: global unhandledrejection → toast notifications
11. Notifications: agent done/error/stall → toasts, 15min stall timer
12. Command palette: all 18 commands (was 10)

+1,198 lines, 13 files. Electrobun now 100% feature-complete vs Tauri v3.
