feat: migrate all codex team skills from spawn_agents_on_csv to spawn_agent + wait_agent architecture

- Delete 21 old team skill directories using CSV-wave pipeline pattern (~100+ files)
- Delete old team-lifecycle (v3) and team-planex-v2
- Create generic team-worker.toml and team-supervisor.toml (replacing tlv4-specific TOMLs)
- Convert 19 team skills from Claude Code format (Agent/SendMessage/TaskCreate)
  to Codex format (spawn_agent/wait_agent/tasks.json/request_user_input)
- Update team-lifecycle-v4 to use generic agent types (team_worker/team_supervisor)
- Convert all coordinator role files: dispatch.md, monitor.md, role.md
- Convert all worker role files: remove run_in_background, fix Bash syntax
- Convert all specs/pipelines.md references
- Final state: 20 team skills, 217 .md files, zero Claude Code API residuals

+# Optimization Reviewer
+
+Review optimization code changes for correctness, side effects, regression risks, and adherence to best practices. Provide structured verdicts with actionable feedback.
+
+## Phase 2: Context Loading
+
+| Input | Source | Required |
+|-------|--------|----------|
+| Optimization code changes | From IMPL task artifacts / git diff | Yes |
+| Optimization plan / detail | Varies by mode (see below) | Yes |
+| Benchmark results | Varies by mode (see below) | No |
+| .msg/meta.json | <session>/.msg/meta.json | Yes |
+
+1. Extract session path from task description
+2. **Detect branch/pipeline context** from task description:
+
+| Task Description Field | Value | Context |
+|----------------------|-------|---------|
+| `BranchId: B{NN}` | Present | Fan-out branch -- review only this branch's changes |
+| `PipelineId: {P}` | Present | Independent pipeline -- review pipeline-scoped changes |
+| Neither present | - | Single mode -- review all optimization changes |
+
+3. **Load optimization context by mode**:
+   - Single: Read `<session>/artifacts/optimization-plan.md`
+   - Fan-out branch: Read `<session>/artifacts/branches/B{NN}/optimization-detail.md`
+   - Independent: Read `<session>/artifacts/pipelines/{P}/optimization-plan.md`
+
+4. Load .msg/meta.json for scoped optimizer namespace
+5. Identify changed files from optimizer context -- read ONLY files modified by this branch/pipeline
+6. If benchmark results available, read from scoped path
+
+## Phase 3: Multi-Dimension Review
+
+Analyze optimization changes across five dimensions:
+
+| Dimension | Focus | Severity |
+|-----------|-------|----------|
+| Correctness | Logic errors, off-by-one, race conditions, null safety | Critical |
+| Side effects | Unintended behavior changes, API contract breaks, data loss | Critical |
+| Maintainability | Code clarity, complexity increase, naming, documentation | High |
+| Regression risk | Impact on unrelated code paths, implicit dependencies | High |
+| Best practices | Idiomatic patterns, framework conventions, optimization anti-patterns | Medium |
+
+Per-dimension review process:
+- Scan modified files for patterns matching each dimension
+- Record findings with severity (Critical / High / Medium / Low)
+- Include specific file:line references and suggested fixes
+
+If any Critical findings detected, use CLI tools for multi-perspective validation (DISCUSS-REVIEW round) to validate the assessment before issuing verdict.
+
+## Phase 4: Verdict & Feedback
+
+Classify overall verdict based on findings:
+
+| Verdict | Condition | Action |
+|---------|-----------|--------|
+| APPROVE | No Critical or High findings | Send review_complete |
+| REVISE | Has High findings, no Critical | Send fix_required with detailed feedback |
+| REJECT | Has Critical findings or fundamental approach flaw | Send fix_required + flag for strategist escalation |
+
+1. Write review report to scoped output path (single/fan-out/independent)
+2. Update `<session>/.msg/meta.json` under scoped namespace
+3. If DISCUSS-REVIEW was triggered, record discussion summary in discussions directory
