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

+# Test Strategist
+
+Analyze change scope, determine test layers (L1-L3), define coverage targets, and generate test strategy document. Create targeted test plans based on scout discoveries and code changes.
+
+## Phase 2: Context & Change Analysis
+
+| Input | Source | Required |
+|-------|--------|----------|
+| Task description | From task subject/description | Yes |
+| Session path | Extracted from task description | Yes |
+| .msg/meta.json | <session>/wisdom/.msg/meta.json | Yes |
+| Discovered issues | meta.json -> discovered_issues | No |
+| Defect patterns | meta.json -> defect_patterns | No |
+
+1. Extract session path from task description
+2. Read .msg/meta.json for scout discoveries and historical patterns
+3. Analyze change scope: `git diff --name-only HEAD~5`
+4. Categorize changed files:
+
+| Category | Pattern |
+|----------|---------|
+| Source | `\.(ts|tsx|js|jsx|py|java|go|rs)$` |
+| Test | `\.(test|spec)\.(ts|tsx|js|jsx)$` or `test_` |
+| Config | `\.(json|yaml|yml|toml|env)$` |
+
+5. Detect test framework from package.json / project files
+6. Check existing coverage baseline from `coverage/coverage-summary.json`
+7. Select analysis mode:
+
+| Total Scope | Mode |
+|-------------|------|
+| <= 5 files + issues | Direct inline analysis |
+| 6-15 | Single CLI analysis |
+| > 15 | Multi-dimension CLI analysis |
+
+## Phase 3: Strategy Generation
+
+**Layer Selection Logic**:
+
+| Condition | Layer | Target |
+|-----------|-------|--------|
+| Has source file changes | L1: Unit Tests | 80% |
+| >= 3 source files OR critical issues | L2: Integration Tests | 60% |
+| >= 3 critical/high severity issues | L3: E2E Tests | 40% |
+| No changes but has scout issues | L1 focused on issue files | 80% |
+
+For CLI-assisted analysis, use:
+```
+PURPOSE: Analyze code changes and scout findings to determine optimal test strategy
+TASK: Classify changed files by risk, map issues to test requirements, identify integration points, recommend test layers with coverage targets
+MODE: analysis
+```
+
+Build strategy document with: scope analysis, layer configs (level, name, target_coverage, focus_files, rationale), priority issues list.
+
+**Validation**: Verify strategy has layers, targets > 0, covers discovered issues, and framework detected.
+
+## Phase 4: Output & Persistence
+
+1. Write strategy to `<session>/strategy/test-strategy.md`
+2. Update `<session>/wisdom/.msg/meta.json`: merge `test_strategy` field with scope, layers, coverage_targets, test_framework
+3. Contribute to wisdom/decisions.md with layer selection rationale
