refactor(agent): reorganize components into professional folder structure

- Rename shared/ → common/ for common utilities
- Split activity/ → git/ (source control) + files/ (file viewer) + panels/
- Consolidate settings/, dialogs/, quick-open/, diagnostics/ → modals/ and panels/
- Reorganize chat/ into messages/, input/, status/, tools/ subfolders
- Move terminal addons from components/ to lib/terminal/
- Update all import paths across codebase
- Add proper index.ts exports for all new folders
