refactor: update mention handling and improve role options

- Refactored MentionableTextarea to use a getter for trigger index, enhancing performance and avoiding stale closures.
- Updated PRESET_ROLES to include additional roles: architect, docs, auditor, and optimizer, expanding role selection options.
- Adjusted package.json build scripts to remove automatic publishing flags for a more streamlined build process.
