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.

+# Synthesizer
+
+Integrate all explorations, analyses, and discussions into final conclusions. Cross-perspective theme extraction, conflict resolution, evidence consolidation, and recommendation prioritization. Pure integration role -- no external tools or CLI calls.
+
+## Phase 2: Context Loading
+
+| Input | Source | Required |
+|-------|--------|----------|
+| Task description | From task subject/description | Yes |
+| Session path | Extracted from task description | Yes |
+| All artifacts | `<session>/explorations/*.json`, `analyses/*.json`, `discussions/*.json` | Yes |
+| Decision trail | From wisdom/.msg/meta.json | No |
+
+1. Extract session path and topic from task description
+2. Read all exploration, analysis, and discussion round files
+3. Load decision trail and current understanding from meta.json
+4. Select synthesis strategy:
+
+| Condition | Strategy |
+|-----------|----------|
+| Single analysis, no discussions | simple (Quick mode summary) |
+| Multiple analyses, >2 discussion rounds | deep (track evolution) |
+| Default | standard (cross-perspective integration) |
+
+## Phase 3: Cross-Perspective Synthesis
+
+Execute synthesis across four dimensions:
+
+**1. Theme Extraction**: Identify convergent themes across all analysis perspectives. Cluster insights by similarity, rank by cross-perspective confirmation count.
+
+**2. Conflict Resolution**: Identify contradictions between perspectives. Present both sides with trade-off analysis when irreconcilable.
+
+**3. Evidence Consolidation**: Deduplicate findings, aggregate by file reference. Map evidence to conclusions with confidence levels:
+
+| Level | Criteria |
+|-------|----------|
+| High | Multiple sources confirm, strong evidence |
+| Medium | Single source or partial evidence |
+| Low | Speculative, needs verification |
+
+**4. Recommendation Prioritization**: Sort all recommendations by priority (high > medium > low), deduplicate, cap at 10.
+
+Integrate decision trail from discussion rounds into final narrative.
+
+## Phase 4: Write Conclusions
+
+1. Write `<session>/conclusions.json`:
+```json
+{
+  "session_id": "...", "topic": "...", "completed": "ISO-8601",
+  "summary": "Executive summary...",
+  "key_conclusions": [{"point": "...", "evidence": "...", "confidence": "high"}],
+  "recommendations": [{"action": "...", "rationale": "...", "priority": "high"}],
+  "open_questions": ["..."],
+  "decision_trail": [{"round": 1, "decision": "...", "context": "..."}],
+  "cross_perspective_synthesis": { "convergent_themes": [], "conflicts_resolved": [], "unique_contributions": [] },
+  "_metadata": { "explorations": 3, "analyses": 3, "discussions": 2, "strategy": "standard" }
+}
+```
+
+2. Append conclusions section to `<session>/discussion.md`:
+```markdown
+## Conclusions
+### Summary / Key Conclusions / Recommendations / Remaining Questions
+## Decision Trail / Current Understanding (Final) / Session Statistics
+```
+
+Update `<session>/wisdom/.msg/meta.json` under `synthesizer` namespace:
+- Read existing -> merge `{ "synthesizer": { conclusion_count, recommendation_count, open_question_count } }` -> write back
