feat: Implement multi-phase project analysis workflow with Mermaid diagram generation and CPCC compliance documentation

- Phase 3: Added Mermaid diagram generation for system architecture, function modules, algorithms, class diagrams, sequence diagrams, and error flows.
- Phase 4: Assembled analysis and diagrams into a structured CPCC-compliant document with section templates and figure numbering.
- Phase 5: Developed compliance review process with iterative refinement based on analysis findings and user feedback.
- Added CPCC compliance requirements and quality standards for project analysis reports.
- Established a comprehensive project analysis skill with detailed execution flow and report types.
- Enhanced error handling and recovery mechanisms throughout the analysis phases.

+# Phase 3: Deep Analysis
+
+Execute deep analysis using Gemini CLI with exploration context.
+
+## Execution
+
+### Step 1: Prepare CLI Prompt
+
+```bash
+ccw cli -p "
+PURPOSE: Generate ${type} analysis report for project
+TASK: 
+  • Analyze project structure and patterns from ${type} perspective
+  • Focus on: ${focus_areas}
+  • Depth level: ${depth}
+  • Key files: ${key_files}
+MODE: analysis
+CONTEXT: @**/* | Exploration results
+EXPECTED: 
+  - Structured analysis
+  - Code references (file:line format)
+  - Mermaid diagram data
+  - Actionable insights
+RULES: $(cat ~/.claude/workflows/cli-templates/protocols/analysis-protocol.md)
+" --tool gemini --mode analysis
+```
+
+### Step 2: Parse Analysis Results
+
+Extract structured data from CLI response:
+
+```javascript
+const deepAnalysis = {
+  findings: [],           // Analyzed findings with confidence scores
+  patterns: [],           // Identified patterns with consistency scores
+  dependencies: [],       // Dependency relationships
+  recommendations: [],    // Prioritized recommendations
+  sections: [],           // Report section data
+  diagram_data: {}        // Data for diagram generation
+};
+```
+
+### Step 3: Validate Analysis Quality
+
+Check analysis completeness:
+
+```javascript
+const qualityChecks = {
+  has_executive_summary: Boolean,
+  focus_areas_covered: config.focus_areas.every(area => analysis.covers(area)),
+  code_references_valid: analysis.references.every(ref => fileExists(ref)),
+  insights_actionable: analysis.insights.filter(i => i.actionable).length > 0
+};
+```
+
+## Output
+
+Save analysis results to `deep-analysis.json`.
