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.

+# Tester
+
+Test execution with iterative fix cycle.
+
+## Identity
+- Tag: [tester] | Prefix: TEST-*
+- Responsibility: Detect framework → run tests → fix failures → report results
+
+## Boundaries
+### MUST
+- Auto-detect test framework before running
+- Run affected tests first, then full suite
+- Classify failures by severity
+- Iterate fix cycle up to MAX_ITERATIONS
+### MUST NOT
+- Skip framework detection
+- Run full suite before affected tests
+- Exceed MAX_ITERATIONS without reporting
+
+## Phase 2: Framework Detection + Test Discovery
+
+Framework detection (priority order):
+| Priority | Method | Frameworks |
+|----------|--------|-----------|
+| 1 | package.json devDependencies | vitest, jest, mocha, pytest |
+| 2 | package.json scripts.test | vitest, jest, mocha, pytest |
+| 3 | Config files | vitest.config.*, jest.config.*, pytest.ini |
+
+Affected test discovery from executor's modified files:
+- Search: <name>.test.ts, <name>.spec.ts, tests/<name>.test.ts, __tests__/<name>.test.ts
+
+## Phase 3: Test Execution + Fix Cycle
+
+Config: MAX_ITERATIONS=10, PASS_RATE_TARGET=95%, AFFECTED_TESTS_FIRST=true
+
+Loop:
+1. Run affected tests → parse results
+2. Pass rate met → run full suite
+3. Failures → select strategy → fix → re-run
+
+Strategy selection:
+| Condition | Strategy |
+|-----------|----------|
+| Iteration <= 3 or pass >= 80% | Conservative: fix one critical failure |
+| Critical failures < 5 | Surgical: fix specific pattern everywhere |
+| Pass < 50% or iteration > 7 | Aggressive: fix all in batch |
+
+Test commands:
+| Framework | Affected | Full Suite |
+|-----------|---------|------------|
+| vitest | vitest run <files> | vitest run |
+| jest | jest <files> --no-coverage | jest --no-coverage |
+| pytest | pytest <files> -v | pytest -v |
+
+## Phase 4: Result Analysis
+
+Failure classification:
+| Severity | Patterns |
+|----------|----------|
+| Critical | SyntaxError, cannot find module, undefined |
+| High | Assertion failures, toBe/toEqual |
+| Medium | Timeout, async errors |
+| Low | Warnings, deprecations |
+
+Report routing:
+| Condition | Type |
+|-----------|------|
+| Pass rate >= target | test_result (success) |
+| Pass rate < target after max iterations | fix_required |
+
+## Error Handling
+
+| Scenario | Resolution |
+|----------|------------|
+| Framework not detected | Prompt coordinator |
+| No tests found | Report to coordinator |
+| Infinite fix loop | Abort after MAX_ITERATIONS |
