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.

+# Test Quality Analyst
+
+Analyze defect patterns, identify coverage gaps, assess GC loop effectiveness, and generate a quality report with actionable recommendations.
+
+## Phase 2: Context Loading
+
+| Input | Source | Required |
+|-------|--------|----------|
+| Task description | From task subject/description | Yes |
+| Session path | Extracted from task description | Yes |
+| Execution results | <session>/results/run-*.json | Yes |
+| Test strategy | <session>/strategy/test-strategy.md | Yes |
+| .msg/meta.json | <session>/wisdom/.msg/meta.json | Yes |
+
+1. Extract session path from task description
+2. Read .msg/meta.json for execution context (executor, generator namespaces)
+3. Read all execution results:
+
+```
+Glob("<session>/results/run-*.json")
+Read("<session>/results/run-001.json")
+```
+
+4. Read test strategy:
+
+```
+Read("<session>/strategy/test-strategy.md")
+```
+
+5. Read test files for pattern analysis:
+
+```
+Glob("<session>/tests/**/*")
+```
+
+## Phase 3: Quality Analysis
+
+**Analysis dimensions**:
+
+1. **Coverage Analysis** -- Aggregate coverage by layer:
+
+| Layer | Coverage | Target | Status |
+|-------|----------|--------|--------|
+| L1 | X% | Y% | Met/Below |
+
+2. **Defect Pattern Analysis** -- Frequency and severity:
+
+| Pattern | Frequency | Severity |
+|---------|-----------|----------|
+| pattern | count | HIGH (>=3) / MEDIUM (>=2) / LOW (<2) |
+
+3. **GC Loop Effectiveness**:
+
+| Metric | Value | Assessment |
+|--------|-------|------------|
+| Rounds | N | - |
+| Coverage Improvement | +/-X% | HIGH (>10%) / MEDIUM (>5%) / LOW (<=5%) |
+
+4. **Coverage Gaps** -- per module/feature:
+   - Area, Current %, Gap %, Reason, Recommendation
+
+5. **Quality Score**:
+
+| Dimension | Score (1-10) | Weight |
+|-----------|-------------|--------|
+| Coverage Achievement | score | 30% |
+| Test Effectiveness | score | 25% |
+| Defect Detection | score | 25% |
+| GC Loop Efficiency | score | 20% |
+
+Write report to `<session>/analysis/quality-report.md`
+
+## Phase 4: Trend Analysis & State Update
+
+**Historical comparison** (if multiple sessions exist):
+
+```
+Glob(".workflow/.team/TST-*/.msg/meta.json")
+```
+
+- Track coverage trends over time
+- Identify defect pattern evolution
+- Compare GC loop effectiveness across sessions
+
+Update `<session>/wisdom/.msg/meta.json` under `analyst` namespace:
+- Merge `{ "analyst": { quality_score, coverage_gaps, top_defect_patterns, gc_effectiveness, recommendations } }`
