feat: Add templates for epics, product brief, and requirements documentation

- Introduced a comprehensive template for generating epics and stories in Phase 5, including an index and individual epic files.
- Created a product brief template for Phase 2 to summarize product vision, goals, and target users.
- Developed a requirements PRD template for Phase 3, outlining functional and non-functional requirements, along with traceability matrices.

feat: Implement tech debt roles for assessment, execution, planning, scanning, validation, and analysis

- Added roles for tech debt assessment, executor, planner, scanner, validator, and analyst, each with defined phases and processes for managing technical debt.
- Each role includes structured input requirements, processing strategies, and output formats to ensure consistency and clarity in tech debt management.

+# Discussant
+
+Process analysis results and user feedback. Execute direction adjustments, deep-dive explorations, or targeted Q&A based on discussion type. Update discussion timeline.
+
+## Phase 2: Context Loading
+
+| Input | Source | Required |
+|-------|--------|----------|
+| Task description | From task subject/description | Yes |
+| Session path | Extracted from task description | Yes |
+| Analysis results | `<session>/analyses/*.json` | Yes |
+| Exploration results | `<session>/explorations/*.json` | No |
+
+1. Extract session path, topic, round, discussion type, user feedback:
+
+| Field | Pattern | Default |
+|-------|---------|---------|
+| sessionFolder | `session:\s*(.+)` | required |
+| topic | `topic:\s*(.+)` | required |
+| round | `round:\s*(\d+)` | 1 |
+| discussType | `type:\s*(.+)` | "initial" |
+| userFeedback | `user_feedback:\s*(.+)` | empty |
+
+2. Read all analysis and exploration results
+3. Aggregate current findings, insights, open questions
+
+## Phase 3: Discussion Processing
+
+Select strategy by discussion type:
+
+| Type | Mode | Description |
+|------|------|-------------|
+| initial | inline | Aggregate all analyses: convergent themes, conflicts, top discussion points |
+| deepen | cli | Use CLI tool to investigate open questions deeper |
+| direction-adjusted | cli | Re-analyze via `ccw cli` from adjusted perspective |
+| specific-questions | cli | Targeted exploration answering user questions |
+
+**initial**: Cross-perspective summary -- identify convergent themes, conflicting views, top 5 discussion points and open questions from all analyses.
+
+**deepen**: Use CLI tool for deep investigation:
+```javascript
+Bash({
+  command: `ccw cli -p "PURPOSE: Investigate open questions and uncertain insights; success = evidence-based findings
+TASK: • Focus on open questions: <questions> • Find supporting evidence • Validate uncertain insights • Document findings
+MODE: analysis
+CONTEXT: @**/* | Memory: Session <session-folder>, previous analyses
+EXPECTED: JSON output with investigation results | Write to <session>/discussions/deepen-<num>.json
+CONSTRAINTS: Evidence-based analysis only
+" --tool gemini --mode analysis --rule analysis-trace-code-execution`,
+  run_in_background: false
+})
+```
+
+**direction-adjusted**: CLI re-analysis from adjusted focus:
+```javascript
+Bash({
+  command: `ccw cli -p "Re-analyze '<topic>' with adjusted focus on '<userFeedback>'" --tool gemini --mode analysis`,
+  run_in_background: false
+})
+```
+
+**specific-questions**: Use CLI tool for targeted Q&A:
+```javascript
+Bash({
+  command: `ccw cli -p "PURPOSE: Answer specific user questions about <topic>; success = clear, evidence-based answers
+TASK: • Answer: <userFeedback> • Provide code references • Explain context
+MODE: analysis
+CONTEXT: @**/* | Memory: Session <session-folder>
+EXPECTED: JSON output with answers and evidence | Write to <session>/discussions/questions-<num>.json
+CONSTRAINTS: Direct answers with code references
+" --tool gemini --mode analysis`,
+  run_in_background: false
+})
+```
+
+## Phase 4: Update Discussion Timeline
+
+1. Write round content to `<session>/discussions/discussion-round-<num>.json`:
+```json
+{
+  "round": 1, "type": "initial", "user_feedback": "...",
+  "updated_understanding": { "confirmed": [], "corrected": [], "new_insights": [] },
+  "new_findings": [], "new_questions": [], "timestamp": "..."
+}
+```
+
+2. Append round section to `<session>/discussion.md`:
+```markdown
+### Round <N> - Discussion (<timestamp>)
+#### Type: <discussType>
+#### User Input: <userFeedback or "(Initial discussion round)">
+#### Updated Understanding
+**Confirmed**: <list> | **Corrected**: <list> | **New Insights**: <list>
+#### New Findings / Open Questions
+```
+
+Update `<session>/wisdom/.msg/meta.json` under `discussant` namespace:
+- Read existing -> merge `{ "discussant": { round, type, new_insight_count, corrected_count } }` -> write back
