Implement Post-Run Verification (#13)

Features:
- Add VerificationService for comprehensive post-run verification
- Implement resource existence validation
- Add permission validation and visibility checks
- Create detailed verification reporting with recommendations

Verification Features:
- Verify all created resources exist
- Check permission inheritance and channel sync status
- Validate @everyone access permissions
- Identify hidden channels and permission issues
- Generate actionable recommendations

Reporting:
- Color-coded verification results
- Detailed summary statistics
- Smart recommendations for common issues
- Clear categorization by resource type

Technical Implementation:
- Created VerificationService with async verification methods
- Added VerificationResult and VerificationFinding records
- Integrated verification into both test mode and normal mode
- Added comprehensive unit tests

Documentation:
- Updated README.md with verification features
- Added example verification output
- Documented all verification capabilities

Testing:
- Added 4 new unit tests for verification functionality
- All 27 tests passing
- No linter errors

Closes #13
