feat: Add Role Analysis Reviewer Agent and validation template

- Introduced Role Analysis Reviewer Agent to validate role analysis outputs against templates and quality standards.
- Created a detailed validation ruleset for the system-architect role, including mandatory and recommended sections.
- Added JSON validation report structure for output.
- Implemented execution command for validation process.

test: Add UX tests for HookCard component

- Created comprehensive tests for HookCard component, focusing on delete confirmation UX pattern.
- Verified confirmation dialog appearance, deletion functionality, and button interactions.
- Ensured proper handling of state updates and visual feedback for enabled/disabled status.

test: Add UX tests for ThemeSelector component

- Developed tests for ThemeSelector component, emphasizing delete confirmation UX pattern.
- Validated confirmation dialog display, deletion actions, and toast notifications for undo functionality.
- Ensured proper management of theme slots and state updates.

feat: Implement useDebounce hook

- Added useDebounce hook to delay expensive computations or API calls, enhancing performance.

feat: Create System Architect Analysis Template

- Developed a comprehensive template for system architect role analysis, covering required sections such as architecture overview, data model, state machine, error handling strategy, observability requirements, configuration model, and boundary scenarios.
- Included examples and templates for each section to guide users in producing SPEC.md-level precision modeling.

+# Executor — Phase 2-4
+
+## Phase 2: Task & Plan Loading
+
+**Objective**: Load plan and determine execution strategy.
+
+1. Load plan.json and .task/TASK-*.json from `<session-folder>/plan/`
+
+**Backend selection** (priority order):
+
+| Priority | Source | Method |
+|----------|--------|--------|
+| 1 | Task metadata | task.metadata.executor field |
+| 2 | Plan default | "Execution Backend:" in plan |
+| 3 | Auto-select | Simple (< 200 chars, no refactor) → agent; Complex → codex |
+
+**Code review selection**:
+
+| Priority | Source | Method |
+|----------|--------|--------|
+| 1 | Task metadata | task.metadata.code_review field |
+| 2 | Plan default | "Code Review:" in plan |
+| 3 | Auto-select | Critical keywords (auth, security, payment) → enabled |
+
+## Phase 3: Code Implementation
+
+**Objective**: Execute implementation across batches.
+
+**Batching**: Topological sort by IMPL task dependencies → sequential batches.
+
+| Backend | Invocation | Use Case |
+|---------|-----------|----------|
+| gemini | `ccw cli --tool gemini --mode write` (foreground) | Simple, direct edits |
+| codex | `ccw cli --tool codex --mode write` (foreground) | Complex, architecture |
+| qwen | `ccw cli --tool qwen --mode write` (foreground) | Alternative backend |
+
+## Phase 4: Self-Validation
+
+| Step | Method | Pass Criteria |
+|------|--------|--------------|
+| Syntax check | `tsc --noEmit` (30s) | Exit code 0 |
+| Acceptance criteria | Match criteria keywords vs implementation | All addressed |
+| Test detection | Find .test.ts/.spec.ts for modified files | Tests identified |
+| Code review (optional) | gemini analysis or codex review | No blocking issues |
+
+**Report**: task ID, status, files modified, validation results, backend used.
+
+## Error Handling
+
+| Scenario | Resolution |
+|----------|------------|
+| Syntax errors | Retry with error context (max 3) |
+| Missing dependencies | Request from coordinator |
+| Backend unavailable | Fallback to alternative tool |
+| Circular dependencies | Abort, report graph |
