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
+
+Run test suites, collect coverage data, and perform automatic fix cycles when tests fail. Implements the execution side of the Generator-Executor (GC) loop.
+
+## Phase 2: Environment Detection
+
+| Input | Source | Required |
+|-------|--------|----------|
+| Task description | From task subject/description | Yes |
+| Session path | Extracted from task description | Yes |
+| .msg/meta.json | <session>/wisdom/.msg/meta.json | Yes |
+| Test strategy | meta.json -> test_strategy | Yes |
+| Generated tests | meta.json -> generated_tests | Yes |
+| Target layer | task description `layer: L1/L2/L3` | Yes |
+
+1. Extract session path and target layer from task description
+2. Read .msg/meta.json for strategy and generated test file list
+3. Detect test command by framework:
+
+| Framework | Command |
+|-----------|---------|
+| vitest | `npx vitest run --coverage --reporter=json --outputFile=test-results.json` |
+| jest | `npx jest --coverage --json --outputFile=test-results.json` |
+| pytest | `python -m pytest --cov --cov-report=json -v` |
+| mocha | `npx mocha --reporter json > test-results.json` |
+| unknown | `npm test -- --coverage` |
+
+4. Get test files from `generated_tests[targetLayer].files`
+
+## Phase 3: Iterative Test-Fix Cycle
+
+**Max iterations**: 5. **Pass threshold**: 95% or all tests pass.
+
+Per iteration:
+1. Run test command, capture output
+2. Parse results: extract passed/failed counts, parse coverage from output or `coverage/coverage-summary.json`
+3. If all pass (0 failures) -> exit loop (success)
+4. If pass rate >= 95% and iteration >= 2 -> exit loop (good enough)
+5. If iteration >= MAX -> exit loop (report current state)
+6. Extract failure details (error lines, assertion failures)
+7. Delegate fix via CLI tool with constraints:
+   - ONLY modify test files, NEVER modify source code
+   - Fix: incorrect assertions, missing imports, wrong mocks, setup issues
+   - Do NOT: skip tests, add `@ts-ignore`, use `as any`
+8. Increment iteration, repeat
+
+## Phase 4: Result Analysis & Output
+
+1. Build result data: layer, framework, iterations, pass_rate, coverage, tests_passed, tests_failed, all_passed
+2. Save results to `<session>/results/run-<layer>.json`
+3. Save last test output to `<session>/results/output-<layer>.txt`
+4. Update `<session>/wisdom/.msg/meta.json` under `execution_results[layer]` and top-level `execution_results.pass_rate`, `execution_results.coverage`
+5. Message type: `tests_passed` if all_passed, else `tests_failed`
