feat: Add coordinator commands and role specifications for UI design team

- Implemented the 'monitor' command for coordinator role to handle monitoring events, task completion, and pipeline management.
- Created role specifications for the coordinator, detailing responsibilities, command execution protocols, and session management.
- Added role specifications for the analyst, discussant, explorer, and synthesizer in the ultra-analyze skill, defining their context loading, analysis, and synthesis processes.

+# Test Generator
+
+Generate test code by layer (L1 unit / L2 integration / L3 E2E). Acts as the Generator in the Generator-Critic loop. Supports revision mode for GC loop iterations.
+
+## Phase 2: Context Loading
+
+| Input | Source | Required |
+|-------|--------|----------|
+| Task description | From task subject/description | Yes |
+| Session path | Extracted from task description | Yes |
+| Test strategy | <session>/strategy/test-strategy.md | Yes |
+| .msg/meta.json | <session>/wisdom/.msg/meta.json | No |
+
+1. Extract session path and layer from task description
+2. Read test strategy:
+
+```
+Read("<session>/strategy/test-strategy.md")
+```
+
+3. Read source files to test (from strategy priority_files, limit 20)
+4. Read .msg/meta.json for framework and scope context
+
+5. Detect revision mode:
+
+| Condition | Mode |
+|-----------|------|
+| Task subject contains "fix" or "revised" | Revision -- load previous failures |
+| Otherwise | Fresh generation |
+
+For revision mode:
+- Read latest result file for failure details
+- Read effective test patterns from .msg/meta.json
+
+6. Read wisdom files if available
+
+## Phase 3: Test Generation
+
+**Strategy selection by complexity**:
+
+| File Count | Strategy |
+|------------|----------|
+| <= 3 files | Direct: inline Write/Edit |
+| 3-5 files | Single code-developer agent |
+| > 5 files | Batch: group by module, one agent per batch |
+
+**Direct generation** (per source file):
+1. Generate test path: `<session>/tests/<layer>/<test-file>`
+2. Generate test code: happy path, edge cases, error handling
+3. Write test file
+
+**Agent delegation** (medium/high complexity):
+
+```
+Task({
+  subagent_type: "code-developer",
+  run_in_background: false,
+  description: "Generate <layer> tests",
+  prompt: "Generate <layer> tests using <framework>...
+  <file-list-with-content>
+  <if-revision: previous failures + effective patterns>
+  Write test files to: <session>/tests/<layer>/"
+})
+```
+
+**Output verification**:
+
+```
+Glob("<session>/tests/<layer>/**/*")
+```
+
+## Phase 4: Self-Validation & State Update
+
+**Validation checks**:
+
+| Check | Method | Action on Fail |
+|-------|--------|----------------|
+| Syntax | `tsc --noEmit` or equivalent | Auto-fix imports/types |
+| File count | Count generated files | Report issue |
+| Import resolution | Check broken imports | Fix import paths |
+
+Update `<session>/wisdom/.msg/meta.json` under `generator` namespace:
+- Merge `{ "generator": { test_files, layer, round, is_revision } }`
