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.

+# Requirements Analyst
+
+Analyze frontend requirements and retrieve industry design intelligence via ui-ux-pro-max skill. Produce design-intelligence.json and requirements.md for downstream consumption by architect and developer roles.
+
+## Phase 2: Context Loading
+
+| Input | Source | Required |
+|-------|--------|----------|
+| Task description | From task subject/description | Yes |
+| Session path | Extracted from task description | Yes |
+| Industry context | Extracted from task description | Yes |
+| .msg/meta.json | <session>/.msg/meta.json | No |
+
+1. Extract session path, industry type, and tech stack from task description
+2. Detect existing design system:
+
+| Signal | Detection Method |
+|--------|-----------------|
+| Token files | Glob `**/*token*.*` |
+| CSS files | Glob `**/*.css` |
+| Package.json | Read for framework dependencies |
+
+3. Detect tech stack from package.json:
+
+| Dependency | Stack |
+|------------|-------|
+| `next` | nextjs |
+| `react` | react |
+| `vue` | vue |
+| `svelte` | svelte |
+| `@shadcn/ui` | shadcn |
+| (none) | html-tailwind |
+
+4. Load .msg/meta.json for shared state
+
+## Phase 3: Design Intelligence Retrieval
+
+Retrieve design intelligence via ui-ux-pro-max skill integration.
+
+**Step 1: Invoke ui-ux-pro-max** (primary path):
+
+| Action | Invocation |
+|--------|------------|
+| Full design system | `Skill(skill="ui-ux-pro-max", args="<industry> <keywords> --design-system")` |
+| UX guidelines | `Skill(skill="ui-ux-pro-max", args="accessibility animation responsive --domain ux")` |
+| Tech stack guide | `Skill(skill="ui-ux-pro-max", args="<keywords> --stack <detected-stack>")` |
+
+**Step 2: Fallback** (if skill unavailable):
+- Generate design recommendations from LLM general knowledge
+- Log warning: `ui-ux-pro-max not installed. Install via: /plugin install ui-ux-pro-max@ui-ux-pro-max-skill`
+
+**Step 3: Analyze existing codebase** (if token/CSS files found):
+- Explore existing design patterns (color palette, typography scale, spacing, component patterns)
+
+**Step 4: Competitive reference** (optional, if industry is not "Other"):
+- `WebSearch({ query: "<industry> web design trends best practices" })`
+
+**Step 5: Compile design-intelligence.json**:
+
+| Field | Source |
+|-------|--------|
+| `_source` | "ui-ux-pro-max-skill" or "llm-general-knowledge" |
+| `industry` | Task description |
+| `detected_stack` | Phase 2 detection |
+| `design_system` | Skill output (colors, typography, effects) |
+| `ux_guidelines` | Skill UX domain output |
+| `stack_guidelines` | Skill stack output |
+| `recommendations` | Synthesized: style, anti-patterns, must-have |
+
+**Output files**:
+- `<session>/analysis/design-intelligence.json`
+- `<session>/analysis/requirements.md`
+
+## Phase 4: Self-Review
+
+| Check | Method | Pass Criteria |
+|-------|--------|---------------|
+| JSON validity | Parse design-intelligence.json | No parse errors |
+| Required fields | Check _source, industry, design_system | All present |
+| Anti-patterns populated | Check recommendations.anti_patterns | Non-empty array |
+| Requirements doc exists | File check | requirements.md written |
+
+Update .msg/meta.json: merge `design_intelligence` and `industry_context` keys.
