tegwick 8179929a4a feat: implement lightweight full text search plugin using SQLite FTS5 (issue #83)
Added comprehensive full text search capabilities as a lightweight plugin.

Key features:
- SQLite FTS5-based search engine with no external dependencies
- Automatic indexing via database triggers for real-time updates
- Advanced query support: phrase search, boolean operators, proximity search
- Complete CLI interface with search commands
- Graceful fallback to LIKE queries when FTS5 unavailable
- Plugin architecture integration for extensibility

CLI Commands:
- `markitect search init` - Initialize search indexes
- `markitect search query` - Perform full text searches
- `markitect search status` - View index statistics
- `markitect search rebuild` - Rebuild indexes from scratch

Search Features:
- Content type filtering (files, schemas, all)
- Result pagination and formatting options
- Query validation and syntax assistance
- Performance optimization and index maintenance

Technical Implementation:
- FTSSearchPlugin: Main search plugin class
- SearchIndexer: FTS5 table management and indexing
- QueryParser: Query optimization and FTS5 syntax conversion
- Comprehensive error handling and fallback mechanisms
- 25 test cases covering all functionality

Documentation includes complete usage guide and examples.
