feat(workflow): add comprehensive planning, resumption, review, status, and test generation commands

- Implemented `/workflow:plan` for creating detailed implementation plans with task decomposition and context gathering.
- Added `/workflow:resume` for intelligent session resumption with automatic progress analysis.
- Introduced `/workflow:review` for executing the final phase of quality validation and generating review reports.
- Developed `/workflow:status` to provide on-demand views of workflow status and task progress.
- Created `/workflow:test-gen` to generate comprehensive test workflows based on completed implementation tasks, ensuring full test coverage.

+
+1. **Validation Checks**
+   - All tasks completed
+   - Tests passing
+   - Code quality metrics
+   - Documentation complete
+
+2. **Generate Review Report**
+   ```markdown
+   # Review Report
+   
+   ## Task Completion
+   - Total: 10
+   - Completed: 10
+   - Success Rate: 100%
+   
+   ## Quality Metrics
+   - Test Coverage: 85%
+   - Code Quality: A
+   - Documentation: Complete
+   
+   ## Issues Found
+   - Minor: 2
+   - Major: 0
+   - Critical: 0
+   ```
+
+3. **Update Session**
+   ```json
+   {
+     "current_phase": "REVIEW",
+     "phases": {
+       "REVIEW": {
+         "status": "completed",
+         "output": "REVIEW.md",
+         "test_results": {
+           "passed": 45,
+           "failed": 0,
+           "coverage": 85
+         }
+       }
+     }
+   }
+   ```
