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 Executor
+
+Execute tests, collect coverage, attempt auto-fix for failures. Acts as the Critic in the Generator-Critic loop. Reports pass rate and coverage for coordinator GC decisions.
+
+## Phase 2: Context Loading
+
+| Input | Source | Required |
+|-------|--------|----------|
+| Task description | From task subject/description | Yes |
+| Session path | Extracted from task description | Yes |
+| Test directory | Task description (Input: <path>) | Yes |
+| Coverage target | Task description (default: 80%) | Yes |
+| .msg/meta.json | <session>/wisdom/.msg/meta.json | No |
+
+1. Extract session path and test directory from task description
+2. Extract coverage target (default: 80%)
+3. Read .msg/meta.json for framework info (from strategist namespace)
+4. Determine test framework:
+
+| Framework | Run Command |
+|-----------|-------------|
+| Jest | `npx jest --coverage --json --outputFile=<session>/results/jest-output.json` |
+| Pytest | `python -m pytest --cov --cov-report=json:<session>/results/coverage.json -v` |
+| Vitest | `npx vitest run --coverage --reporter=json` |
+
+5. Find test files to execute:
+
+```
+Glob("<session>/<test-dir>/**/*")
+```
+
+## Phase 3: Test Execution + Fix Cycle
+
+**Iterative test-fix cycle** (max 3 iterations):
+
+| Step | Action |
+|------|--------|
+| 1 | Run test command |
+| 2 | Parse results: pass rate + coverage |
+| 3 | pass_rate >= 0.95 AND coverage >= target -> success, exit |
+| 4 | Extract failing test details |
+| 5 | Delegate fix to CLI tool (gemini write mode) |
+| 6 | Increment iteration; >= 3 -> exit with failures |
+
+```
+Bash("<test-command> 2>&1 || true")
+```
+
+**Auto-fix delegation** (on failure):
+
+```
+Bash({
+  command: `ccw cli -p "PURPOSE: Fix test failures to achieve pass rate >= 0.95; success = all tests pass
+TASK: • Analyze test failure output • Identify root causes • Fix test code only (not source) • Preserve test intent
+MODE: write
+CONTEXT: @<session>/<test-dir>/**/* | Memory: Test framework: <framework>, iteration <N>/3
+EXPECTED: Fixed test files with: corrected assertions, proper async handling, fixed imports, maintained coverage
+CONSTRAINTS: Only modify test files | Preserve test structure | No source code changes
+Test failures:
+<test-output>" --tool gemini --mode write --cd <session>`,
+  run_in_background: false
+})
+```
+
+**Save results**: `<session>/results/run-<N>.json`
+
+## Phase 4: Defect Pattern Extraction & State Update
+
+**Extract defect patterns from failures**:
+
+| Pattern Type | Detection Keywords |
+|--------------|-------------------|
+| Null reference | "null", "undefined", "Cannot read property" |
+| Async timing | "timeout", "async", "await", "promise" |
+| Import errors | "Cannot find module", "import" |
+| Type mismatches | "type", "expected", "received" |
+
+**Record effective test patterns** (if pass_rate > 0.8):
+
+| Pattern | Detection |
+|---------|-----------|
+| Happy path | "should succeed", "valid input" |
+| Edge cases | "edge", "boundary", "limit" |
+| Error handling | "should fail", "error", "throw" |
+
+Update `<session>/wisdom/.msg/meta.json` under `executor` namespace:
+- Merge `{ "executor": { pass_rate, coverage, defect_patterns, effective_patterns, coverage_history_entry } }`
