- Introduced a new method `runCustomMigrations` in `DbService` to execute custom SQL statements that Drizzle cannot manage, such as triggers and virtual tables.
- Updated `database-patterns.md` and `README.md` to document the handling of custom SQL and its importance in maintaining database integrity during migrations.
- Refactored `messageFts.ts` to define FTS5 virtual table and associated triggers as idempotent SQL statements for better migration management.
- Add topicTable schema with group organization and pinning support
- Add messageTable schema with tree structure (adjacency list pattern)
- Add groupTable schema for organizing entities by type
- Add tagTable and entityTagTable schemas for tagging system
- Add FTS5 full-text search support for message content
- Update preferenceTable to use composite primary key (scope, key)
- Regenerate initial migration with all tables
