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 Strategist
+
+Analyze bottleneck reports and baseline metrics to design a prioritized optimization plan with concrete strategies, expected improvements, and risk assessments.
+
+## Phase 2: Analysis Loading
+
+| Input | Source | Required |
+|-------|--------|----------|
+| Bottleneck report | <session>/artifacts/bottleneck-report.md | Yes |
+| Baseline metrics | <session>/artifacts/baseline-metrics.json | Yes |
+| .msg/meta.json | <session>/.msg/meta.json | Yes |
+| Wisdom files | <session>/wisdom/patterns.md | No |
+
+1. Extract session path from task description
+2. Read bottleneck report -- extract ranked bottleneck list with severities
+3. Read baseline metrics -- extract current performance numbers
+4. Load .msg/meta.json for profiler findings (project_type, scope)
+5. Assess overall optimization complexity:
+
+| Bottleneck Count | Severity Mix | Complexity |
+|-----------------|-------------|------------|
+| 1-2 | All Medium | Low |
+| 2-3 | Mix of High/Medium | Medium |
+| 3+ or any Critical | Any Critical present | High |
+
+## Phase 3: Strategy Formulation
+
+For each bottleneck, select optimization approach by type:
+
+| Bottleneck Type | Strategies | Risk Level |
+|----------------|-----------|------------|
+| CPU hotspot | Algorithm optimization, memoization, caching, worker threads | Medium |
+| Memory leak/bloat | Pool reuse, lazy initialization, WeakRef, scope cleanup | High |
+| I/O bound | Batching, async pipelines, streaming, connection pooling | Medium |
+| Network latency | Request coalescing, compression, CDN, prefetching | Low |
+| Rendering | Virtualization, memoization, CSS containment, code splitting | Medium |
+| Database | Index optimization, query rewriting, caching layer, denormalization | High |
+
+Prioritize optimizations by impact/effort ratio:
+
+| Priority | Criteria |
+|----------|----------|
+| P0 (Critical) | High impact + Low effort -- quick wins |
+| P1 (High) | High impact + Medium effort |
+| P2 (Medium) | Medium impact + Low effort |
+| P3 (Low) | Low impact or High effort -- defer |
+
+If complexity is High, use CLI tools for multi-perspective analysis (DISCUSS-OPT round) to evaluate trade-offs between competing strategies before finalizing the plan.
+
+Define measurable success criteria per optimization (target metric value or improvement %).
+
+## Phase 4: Plan Output
+
+1. Write optimization plan to `<session>/artifacts/optimization-plan.md`:
+
+   Each optimization MUST have a unique OPT-ID and self-contained detail block:
+
+   ```markdown
+   ### OPT-001: <title>
+   - Priority: P0
+   - Target bottleneck: <bottleneck from report>
+   - Target files: <file-list>
+   - Strategy: <selected approach>
+   - Expected improvement: <metric> by <X%>
+   - Risk level: <Low/Medium/High>
+   - Success criteria: <specific threshold to verify>
+   - Implementation guidance:
+     1. <step 1>
+     2. <step 2>
+     3. <step 3>
+
+   ### OPT-002: <title>
+   ...
+   ```
+
+   Requirements:
+   - Each OPT-ID is sequentially numbered (OPT-001, OPT-002, ...)
+   - Each optimization must be **non-overlapping** in target files
+   - Implementation guidance must be self-contained
+
+2. Update `<session>/.msg/meta.json` under `strategist` namespace:
+   - Read existing -> merge -> write back with optimization metadata
+
+3. If DISCUSS-OPT was triggered, record discussion summary in `<session>/discussions/DISCUSS-OPT.md`
