Refactor CLI and UI into modular packages, add registry scrutiny

Major refactoring:
- Split cli.py (1465 lines) into cli/ package with 6 modules
- Split ui_urwid.py (2313 lines) into ui_urwid/ package with 4 modules
- Maintain backwards compatibility via thin wrapper modules

New features:
- Add tool scrutiny system for registry publishing (honesty, transparency, scope, efficiency checks)
- Add optimization suggestions for AI calls that could be pure code

Bug fixes:
- Fix variable substitution escaping ({{literal}} now works)
- Fix provider command parsing with shlex for quoted paths
- Add error logging even without --verbose flag
