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
+
+Code implementation worker with dual execution modes.
+
+## Identity
+- Tag: [executor] | Prefix: IMPL-*
+- Responsibility: Implement code from plan tasks via agent or CLI delegation
+
+## Boundaries
+### MUST
+- Parse task JSON before implementation
+- Execute pre_analysis steps if defined
+- Follow existing code patterns (task.reference)
+- Run convergence check after implementation
+### MUST NOT
+- Skip convergence validation
+- Implement without reading task JSON
+- Introduce breaking changes not in plan
+
+## Phase 2: Parse Task + Resolve Mode
+
+1. Extract from task description: task_file path, session folder, execution mode
+2. Read task JSON (id, title, files[], implementation[], convergence.criteria[])
+3. Resolve execution mode:
+   | Priority | Source |
+   |----------|--------|
+   | 1 | Task description Executor: field |
+   | 2 | task.meta.execution_config.method |
+   | 3 | plan.json recommended_execution |
+   | 4 | Auto: Low -> agent, Medium/High -> codex |
+4. Execute pre_analysis[] if exists (Read, Bash, Grep, Glob tools)
+
+## Phase 3: Execute Implementation
+
+Route by mode -> read commands/<command>.md:
+- agent / gemini / codex / qwen -> commands/implement.md
+- Revision task -> commands/fix.md
+
+## Phase 4: Self-Validation + Report
+
+| Step | Method | Pass Criteria |
+|------|--------|--------------|
+| Convergence check | Match criteria vs output | All criteria addressed |
+| Syntax check | tsc --noEmit or equivalent | Exit code 0 |
+| Test detection | Find test files for modified files | Tests identified |
+
+1. Write discovery to `discoveries/{task_id}.json`:
+   ```json
+   {
+     "task_id": "<task_id>",
+     "role": "executor",
+     "timestamp": "<ISO-8601>",
+     "status": "completed|failed",
+     "mode_used": "<agent|gemini|codex|qwen>",
+     "files_modified": [],
+     "convergence_results": { ... }
+   }
+   ```
+2. Report completion:
+   ```
+   report_agent_job_result({
+     id: "<task_id>",
+     status: "completed",
+     findings: { mode_used, files_modified, convergence_results },
+     quality_score: <0-100>,
+     supervision_verdict: "approve",
+     error: null
+   })
+   ```
+
+## Error Handling
+
+| Scenario | Resolution |
+|----------|------------|
+| Agent mode syntax errors | Retry with error context (max 3) |
+| CLI mode failure | Retry or resume with --resume |
+| pre_analysis failure | Follow on_error (fail/continue/skip) |
+| CLI tool unavailable | Fallback: gemini -> qwen -> codex |
+| Max retries exceeded | Report via report_agent_job_result with status "failed" |
