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 Generator
+
+Generate test code according to strategist's strategy and layers. Support L1 unit tests, L2 integration tests, L3 E2E tests. Follow project's existing test patterns and framework conventions.
+
+## Phase 2: Strategy & Pattern Loading
+
+| 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 |
+| Test strategy | meta.json -> test_strategy | Yes |
+| Target layer | task description `layer: L1/L2/L3` | Yes |
+
+1. Extract session path and target layer from task description
+2. Read .msg/meta.json for test strategy (layers, coverage targets)
+3. Determine if this is a GC fix task (subject contains "fix")
+4. Load layer config from strategy: level, name, target_coverage, focus_files
+5. Learn existing test patterns -- find 3 similar test files via Glob(`**/*.{test,spec}.{ts,tsx,js,jsx}`)
+6. Detect test conventions: file location (colocated vs __tests__), import style, describe/it nesting, framework (vitest/jest/pytest)
+
+## Phase 3: Test Code Generation
+
+**Mode selection**:
+
+| Condition | Mode |
+|-----------|------|
+| GC fix task | Read failure info from `<session>/results/run-<layer>.json`, fix failing tests only |
+| <= 3 focus files | Direct: inline Read source -> Write test file |
+| > 3 focus files | Batch by module, delegate via CLI tool |
+
+**Direct generation flow** (per source file):
+1. Read source file content, extract exports
+2. Determine test file path following project conventions
+3. If test exists -> analyze missing cases -> append new tests via Edit
+4. If no test -> generate full test file via Write
+5. Include: happy path, edge cases, error cases per export
+
+**GC fix flow**:
+1. Read execution results and failure output from results directory
+2. Read each failing test file
+3. Fix assertions, imports, mocks, or test setup
+4. Do NOT modify source code, do NOT skip/ignore tests
+
+**General rules**:
+- Follow existing test patterns exactly (imports, naming, structure)
+- Target coverage per layer config
+- Do NOT use `any` type assertions or `@ts-ignore`
+
+## Phase 4: Self-Validation & Output
+
+1. Collect generated/modified test files
+2. Run syntax check (TypeScript: `tsc --noEmit`, or framework-specific)
+3. Auto-fix syntax errors (max 3 attempts)
+4. Write test metadata to `<session>/wisdom/.msg/meta.json` under `generated_tests[layer]`:
+   - layer, files list, count, syntax_clean, mode, gc_fix flag
+5. Message type: `tests_generated` for new, `tests_revised` for GC fix iterations
