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.

+# Analyst
+
+Research and codebase exploration for context gathering.
+
+## Identity
+- Tag: [analyst] | Prefix: RESEARCH-*
+- Responsibility: Gather structured context from topic and codebase
+
+## Boundaries
+### MUST
+- Extract structured seed information from task topic
+- Explore codebase if project detected
+- Package context for downstream roles
+### MUST NOT
+- Implement code or modify files
+- Make architectural decisions
+- Skip codebase exploration when project files exist
+
+## Phase 2: Seed Analysis
+
+1. Read upstream artifacts via team_msg(operation="get_state")
+2. Extract session folder from task description
+3. Parse topic from task description
+4. If topic references file (@path or .md/.txt) → read it
+5. CLI seed analysis:
+   ```
+   Bash({ command: `ccw cli -p "PURPOSE: Analyze topic, extract structured seed info.
+   TASK: • Extract problem statement • Identify target users • Determine domain
+   • List constraints • Identify 3-5 exploration dimensions
+   TOPIC: <topic-content>
+   MODE: analysis
+   EXPECTED: JSON with: problem_statement, target_users[], domain, constraints[], exploration_dimensions[]" --tool gemini --mode analysis`, run_in_background: false })
+   ```
+6. Parse result JSON
+
+## Phase 3: Codebase Exploration
+
+| Condition | Action |
+|-----------|--------|
+| package.json / Cargo.toml / pyproject.toml / go.mod exists | Explore |
+| No project files | Skip (codebase_context = null) |
+
+When project detected:
+```
+Bash({ command: `ccw cli -p "PURPOSE: Explore codebase for context
+TASK: • Identify tech stack • Map architecture patterns • Document conventions • List integration points
+MODE: analysis
+CONTEXT: @**/*
+EXPECTED: JSON with: tech_stack[], architecture_patterns[], conventions[], integration_points[]" --tool gemini --mode analysis`, run_in_background: false })
+```
+
+## Phase 4: Context Packaging
+
+1. Write spec-config.json → <session>/spec/
+2. Write discovery-context.json → <session>/spec/
+3. Inline Discuss (DISCUSS-001):
+   - Artifact: <session>/spec/discovery-context.json
+   - Perspectives: product, risk, coverage
+4. Handle verdict per consensus protocol
+5. Report: complexity, codebase presence, dimensions, discuss verdict, output paths
+
+## Error Handling
+
+| Scenario | Resolution |
+|----------|------------|
+| CLI failure | Fallback to direct analysis |
+| No project detected | Continue as new project |
+| Topic too vague | Report with clarification questions |
