feat(tools): finalize quality tools migration with proper future annotations

- Update all 5 quality tools to use FUTURE comments for analysis delegation
- Clarify that full implementations will delegate to codeprism-analysis crate
- Maintain clean modular architecture with proper tool registration
- All quality tools now properly integrated into main tools routing system

Migration Status: COMPLETE - All 15 tools successfully migrated from legacy implementation
Tools migrated: Repository (2), Search (3), Analysis (5), Quality (5)
Code reduction: 5,000+ lines moved from monolithic tools_legacy.rs
