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.

+# Pipeline Definitions — team-brainstorm
+
+## Available Pipelines
+
+### Quick Pipeline (3 beats, strictly serial)
+
+```
+IDEA-001 → CHALLENGE-001 → SYNTH-001
+[ideator]   [challenger]   [synthesizer]
+```
+
+### Deep Pipeline (6 beats, Generator-Critic loop)
+
+```
+IDEA-001 → CHALLENGE-001 → IDEA-002(fix) → CHALLENGE-002 → SYNTH-001 → EVAL-001
+```
+
+GC loop check: if critique.severity >= HIGH → create IDEA-fix → CHALLENGE-2 → SYNTH; else skip to SYNTH
+
+### Full Pipeline (7 tasks, fan-out parallel ideation + GC)
+
+```
+[IDEA-001 + IDEA-002 + IDEA-003](parallel) → CHALLENGE-001(batch) → IDEA-004(fix) → SYNTH-001 → EVAL-001
+```
+
+## Task Metadata Registry
+
+| Task ID | Role | Phase | Dependencies | Description |
+|---------|------|-------|-------------|-------------|
+| IDEA-001 | ideator | generate | (none) | Multi-angle idea generation |
+| IDEA-002 | ideator | generate | (none) | Parallel angle (Full pipeline only) |
+| IDEA-003 | ideator | generate | (none) | Parallel angle (Full pipeline only) |
+| CHALLENGE-001 | challenger | challenge | IDEA-001 (or all IDEA-*) | Devil's advocate critique and feasibility challenge |
+| IDEA-004 | ideator | gc-fix | CHALLENGE-001 | Revision based on critique (GC loop, if triggered) |
+| CHALLENGE-002 | challenger | gc-fix | IDEA-004 | Re-critique of revised ideas (GC loop round 2) |
+| SYNTH-001 | synthesizer | synthesize | last CHALLENGE-* | Cross-idea integration, theme extraction, conflict resolution |
+| EVAL-001 | evaluator | evaluate | SYNTH-001 | Scoring, ranking, priority recommendation, final selection |
+
+## Checkpoints
+
+| Trigger | Location | Behavior |
+|---------|----------|----------|
+| Generator-Critic loop | After CHALLENGE-* | If severity >= HIGH → create IDEA-fix task; else proceed to SYNTH |
+| GC loop limit | Max 2 rounds | Exceeds limit → force convergence to SYNTH |
+| Pipeline stall | No ready + no running | Check missing tasks, report to user |
+
+## Completion Conditions

+|------|---------------------|
+| quick | All 3 tasks completed |
+| deep | All 6 tasks (+ any skipped GC tasks) completed |
