fix: update enhancement mode descriptions for accuracy

- Default: Remove "lists" mention since we preserve natural flow
- Prompts: Emphasize "clear, actionable" output
- Email: Specify all components (subject, greeting, signature)
- Commit: Add examples of conventional types (feat, fix, docs)

Descriptions now accurately reflect what each mode does.
