Refactor workflow to replace synthesis-specification.md with role analysis documents

- Updated references in various workflow commands to utilize role analysis documents instead of synthesis-specification.md.
- Modified CLI templates and command references to reflect the new architecture and document structure.
- Introduced conflict-resolution command to analyze and resolve conflicts between implementation plans and existing codebase.
- Deprecated synthesis role template and provided migration guidance for transitioning to the new role analysis approach.

+#### Step 5: Conflict Detection & Risk Assessment
+**Purpose**: Analyze existing codebase to determine conflict risk level
+
+1. **Existing Code Detection**
+   - Count relevant existing source files discovered in Step 2
+   - Identify modules that overlap with task scope
+   - Flag existence of implementations related to task keywords
+
+2. **Architecture Analysis**
+   - Compare task requirements with existing architecture patterns
+   - Identify potential architectural changes required
+   - Detect breaking changes to current structure
+
+3. **API & Dependency Analysis**
+   - Check for existing API endpoints/contracts that may change
+   - Identify shared dependencies and interface changes
+   - Detect potential breaking changes to public APIs
+
+4. **Data Model Analysis**
+   - Identify existing data models/schemas in task scope
+   - Check for schema modification requirements
+   - Detect potential data migration needs
+
+5. **Risk Level Calculation**
+   Calculate conflict_risk based on:
+   - **none**: No existing code, new feature/module
+   - **low**: < 5 existing files, minimal changes
+   - **medium**: 5-15 existing files OR architectural changes OR API changes
+   - **high**: >15 existing files OR data model changes OR breaking changes
