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.

+# Evaluator
+
+Scoring, ranking, and final selection. Multi-dimension evaluation of synthesized proposals with weighted scoring and priority recommendations.
+
+## Phase 2: Context Loading
+
+| Input | Source | Required |
+|-------|--------|----------|
+| Session folder | Task description (Session: line) | Yes |
+| Synthesis results | <session>/synthesis/*.md files | Yes |
+| All ideas | <session>/ideas/*.md files | No (for context) |
+| All critiques | <session>/critiques/*.md files | No (for context) |
+
+1. Extract session path from task description (match "Session: <path>")
+2. Glob synthesis files from <session>/synthesis/
+3. Read all synthesis files for evaluation
+4. Optionally read ideas and critiques for full context
+
+## Phase 3: Evaluation and Scoring
+
+**Scoring Dimensions**:
+
+| Dimension | Weight | Focus |
+|-----------|--------|-------|
+| Feasibility | 30% | Technical feasibility, resource needs, timeline |
+| Innovation | 25% | Novelty, differentiation, breakthrough potential |
+| Impact | 25% | Scope of impact, value creation, problem resolution |
+| Cost Efficiency | 20% | Implementation cost, risk cost, opportunity cost |
+
+**Weighted Score**: `(Feasibility * 0.30) + (Innovation * 0.25) + (Impact * 0.25) + (Cost * 0.20)`
+
+**Per-Proposal Evaluation**:
+- Score each dimension (1-10) with rationale
+- Overall recommendation: Strong Recommend / Recommend / Consider / Pass
+
+**Output**: Write to `<session>/evaluation/evaluation-<num>.md`
+- Sections: Input summary, Scoring Matrix (ranked table), Detailed Evaluation per proposal, Final Recommendation, Action Items, Risk Summary
+
+## Phase 4: Consistency Check
+
+| Check | Pass Criteria | Action on Failure |
+|-------|---------------|-------------------|
+| Score spread | max - min >= 0.5 (with >1 proposal) | Re-evaluate differentiators |
+| No perfect scores | Not all 10s | Adjust to reflect critique findings |
+| Ranking deterministic | Consistent ranking | Verify calculation |
+
+After passing checks, update shared state:
+- Set .msg/meta.json evaluation_scores
+- Each entry: title, weighted_score, rank, recommendation
