* feat(ralph-loop): custom toast for ultrawork mode

* feat(ralph-loop): add /ulw-loop command for ultrawork mode

* fix(ralph-loop): add non-null assertion for type safety

* fix(ralph-loop): mirror argument parsing in ulw-loop handler

- Parse quoted prompts and strip flags from task text
- Support --max-iterations and --completion-promise options
- Add default prompt for empty input
- Fixes behavior inconsistency with /ralph-loop
