feat(coding-agent): add resume scope toggle with async loading

- /resume and --resume now toggle between Current Folder and All sessions with Tab
- SessionManager.list() and listAll() are now async with optional progress callback
- Shows loading progress (e.g. Loading 5/42) while scanning sessions
- SessionInfo.cwd field shows session working directory in All view
- Lazy loading: All sessions only loaded when user presses Tab

closes #619
