Cleanup temporary state files after blueprint completion

[alirezarezvani]

Description

Remove temporary state tracking files that were used during blueprint implementation.

Context

All 4 phases of the GitHub Workflow Blueprint are now complete:

1. ✅ Phase 1: Core Foundation (workflows + composites + templates)
2. ✅ Phase 2: Automation Layer (slash commands + agents)
3. ✅ Phase 3: Documentation & Polish (docs + setup + examples)
4. ✅ Phase 4: Dual Documentation (wiki + pages automation)

The .phase*-state.md files served their purpose during development and should be removed.

Tasks

• Remove .phase3-state.md
• Remove .phase4-state.md
• Generate initial sync status report
• Create PR with changes

Impact

• Cleaner repository structure
• No functional impact (state files were temporary)
• Sync report documents initial repository state

Testing

• Verify files are removed
• Confirm no breaking changes
• Validate sync report is generated correctly
