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

+# Executor
+
+Wave-based code implementation per phase. Reads IMPL-*.json task files, computes execution waves from the dependency graph, delegates each task to CLI tool for code generation. Produces summary-{IMPL-ID}.md per task.
+
+## Phase 2: Context Loading
+
+| Input | Source | Required |
+|-------|--------|----------|
+| Task JSONs | <session>/phase-{N}/.task/IMPL-*.json | Yes |
+| Prior summaries | <session>/phase-{1..N-1}/summary-*.md | No |
+| Wisdom | <session>/wisdom/ | No |
+
+1. Glob `<session>/phase-{N}/.task/IMPL-*.json`, error if none found
+2. Parse each task JSON: extract id, description, depends_on, files, convergence, implementation
+3. Compute execution waves from dependency graph:
+   - Wave 1: tasks with no dependencies
+   - Wave N: tasks whose all deps are in waves 1..N-1
+   - Force-assign if circular (break at lowest-numbered task)
+4. Load prior phase summaries for cross-task context
+
+## Phase 3: Wave-Based Implementation
+
+Execute waves sequentially, tasks within each wave can be parallel.
+
+**Strategy selection**:
+
+| Task Count | Strategy |
+|------------|----------|
+| <= 2 | Direct: inline Edit/Write |
+| 3-5 | Single CLI tool call for all |
+| > 5 | Batch: one CLI tool call per module group |
+
+**Per task**:
+1. Build prompt from task JSON: description, files, implementation steps, convergence criteria
+2. Include prior summaries and wisdom as context
+3. Delegate to CLI tool:
+   ```
+   Bash({
+     command: `ccw cli -p "PURPOSE: Implement task ${taskId}: ${description}
+   TASK: ${implementationSteps}
+   MODE: write
+   CONTEXT: @${files.join(' @')} | Memory: ${priorSummaries}
+   EXPECTED: Working code changes matching convergence criteria
+   CONSTRAINTS: ${convergenceCriteria}" --tool gemini --mode write`
+   })
+   ```
+4. Write `<session>/phase-{N}/summary-{IMPL-ID}.md` with: task ID, affected files, changes made, status
+
+**Between waves**: report wave progress via team_msg (type: exec_progress)
+
+## Phase 4: Self-Validation
+
+| Check | Method | Pass Criteria |
+|-------|--------|---------------|
+| Affected files exist | `test -f <path>` for each file in summary | All present |
+| TypeScript syntax | `npx tsc --noEmit` (if tsconfig.json exists) | No errors |
+| Lint | `npm run lint` (best-effort) | No critical errors |
+
+Log errors via team_msg but do NOT fix — verifier handles gap detection.
