feat: Add wiki integration to task management

- Implemented a multi-select dropdown for associating tasks with wiki entries in the task edit form.
- Enhanced task popup to display related wiki entries with visibility controls based on user permissions.
- Updated the wiki main view to support bulk actions for categories, including deletion and search functionality.
- Created a new database migration for establishing many-to-many relationships between tasks and wiki entries.
- Improved styling for wiki components to enhance user experience.
- Added a new AGENTS.md file to outline communication and change management protocols.
