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.

+# Testing Pipelines
+
+Pipeline definitions and task registry for team-testing.
+
+## Pipeline Selection
+
+| Condition | Pipeline |
+|-----------|----------|
+| fileCount <= 3 AND moduleCount <= 1 | targeted |
+| fileCount <= 10 AND moduleCount <= 3 | standard |
+| Otherwise | comprehensive |
+
+## Pipeline Definitions
+
+### Targeted Pipeline (3 tasks, serial)
+
+```
+STRATEGY-001 -> TESTGEN-001 -> TESTRUN-001
+```
+
+| Task ID | Role | Dependencies | Layer | Description |
+|---------|------|-------------|-------|-------------|
+| STRATEGY-001 | strategist | (none) | — | Analyze changes, define test strategy |
+| TESTGEN-001 | generator | STRATEGY-001 | L1 | Generate L1 unit tests |
+| TESTRUN-001 | executor | TESTGEN-001 | L1 | Execute L1 tests, collect coverage |
+
+### Standard Pipeline (6 tasks, progressive layers)
+
+```
+STRATEGY-001 -> TESTGEN-001 -> TESTRUN-001 -> TESTGEN-002 -> TESTRUN-002 -> TESTANA-001
+```
+
+| Task ID | Role | Dependencies | Layer | Description |
+|---------|------|-------------|-------|-------------|
+| STRATEGY-001 | strategist | (none) | — | Analyze changes, define test strategy |
+| TESTGEN-001 | generator | STRATEGY-001 | L1 | Generate L1 unit tests |
+| TESTRUN-001 | executor | TESTGEN-001 | L1 | Execute L1 tests, collect coverage |
+| TESTGEN-002 | generator | TESTRUN-001 | L2 | Generate L2 integration tests |
+| TESTRUN-002 | executor | TESTGEN-002 | L2 | Execute L2 tests, collect coverage |
+| TESTANA-001 | analyst | TESTRUN-002 | — | Defect pattern analysis, quality report |
+
+### Comprehensive Pipeline (8 tasks, parallel windows)
+
+```
+STRATEGY-001 -> [TESTGEN-001 || TESTGEN-002] -> [TESTRUN-001 || TESTRUN-002] -> TESTGEN-003 -> TESTRUN-003 -> TESTANA-001
+```
+
+| Task ID | Role | Dependencies | Layer | Description |
+|---------|------|-------------|-------|-------------|
+| STRATEGY-001 | strategist | (none) | — | Analyze changes, define test strategy |
+| TESTGEN-001 | generator-1 | STRATEGY-001 | L1 | Generate L1 unit tests (parallel) |
+| TESTGEN-002 | generator-2 | STRATEGY-001 | L2 | Generate L2 integration tests (parallel) |
+| TESTRUN-001 | executor-1 | TESTGEN-001 | L1 | Execute L1 tests (parallel) |
+| TESTRUN-002 | executor-2 | TESTGEN-002 | L2 | Execute L2 tests (parallel) |
+| TESTGEN-003 | generator | TESTRUN-001, TESTRUN-002 | L3 | Generate L3 E2E tests |
+| TESTRUN-003 | executor | TESTGEN-003 | L3 | Execute L3 tests, collect coverage |
+| TESTANA-001 | analyst | TESTRUN-003 | — | Defect pattern analysis, quality report |
+
+## GC Loop (Generator-Critic)
+
+Generator and executor iterate per test layer:
+
+```
+TESTGEN -> TESTRUN -> (if pass_rate < 0.95 OR coverage < target) -> TESTGEN-fix -> TESTRUN-fix
+                      (if pass_rate >= 0.95 AND coverage >= target) -> next layer or TESTANA
+```
+
+- Max iterations: 3 per layer
+- After 3 iterations: accept current state with warning
+
+## Coverage Targets
+
+| Layer | Name | Default Target |
+|-------|------|----------------|
+| L1 | Unit Tests | 80% |
+| L2 | Integration Tests | 60% |
+| L3 | E2E Tests | 40% |
