test(phase-5): implement Phase 5 validation and testing

Completed comprehensive validation and testing of all system components
as part of Phase 5: Validation and Testing.

## What Was Tested

### Test 1: Cursor Rules ✅
- Verified rules file exists and is properly structured
- Confirmed all required sections present
- Validated phase documentation synchronization rules

### Test 2: KB System ✅
- Verified KB directory structure complete
- Confirmed all three templates exist with complete frontmatter
- Tested index generation script (works correctly)
- Created test KB file and verified indexing
- Tested changelog update process

### Test 3: Phase Documentation ✅
- Verified phase structure
- Tested blueprint modification synchronization
- Confirmed changelog updates automatically per Cursor rules

### Test 4: Gitea Actions Workflows ⏸️
- Verified workflow files exist and syntax is valid
- Validated workflow configuration (triggers, paths, permissions)
- Workflow execution pending runner configuration
- Runner setup request documented in docs/issues/

### Test 5: LLM Prompts ✅
- Verified prompt files exist
- Confirmed prompt structure follows documentation
- Validated prompt content is complete

## Test Results

**Total Tests**: 18
**Passed**: 17
**Pending**: 1 (requires runners)
**Pass Rate**: 94.4%

## Files Created

### Phase 5 Documentation
-  - Phase blueprint
-  - Task tracking
-  - Change history
-  - ADRs
-  - Detailed test results
-  - Final validation report

### Test Artifacts
-  - Test KB file for validation

## Files Modified

-  - Added Phase 5 test file entry
-  - Regenerated with test file (9 files indexed)
-  - Version updated (1.0 → 1.1) for sync test
-  - Updated per synchronization rules

## Key Findings

✅ **All tested components working correctly**:
- Cursor rules structure and content
- KB system file creation and indexing
- Phase documentation synchronization
- Index generation script
- KB changelog updates
- LLM prompt file structure

⏸️ **Pending Runner Configuration**:
- Gitea Actions workflow execution (requires runners)
- KB lint workflow validation
- KB index auto-update workflow

## Phase Status

**Phase 5 Status**: ✅ Complete (with runner requirement noted)

All components that can be tested without runners have been validated
and are working correctly. Workflow execution tests will be completed
once Gitea Actions runners are configured.

## Next Steps

1. Configure Gitea Actions runners (when available)
2. Complete workflow execution tests
3. Proceed to Phase 6: Customization and Final Verification
