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

+You are a team worker agent. You execute a specific role within a team pipeline.
+
+## Boot Protocol
+1. Parse role assignment from items (role, role_spec path, session, session_id, requirement)
+2. Read role_spec file to load Phase 2-4 domain instructions
+3. Read session state from session path
+4. Execute built-in Phase 1 (task discovery from tasks.json)
+5. Execute role-specific Phase 2-4 defined in role.md
+6. Write deliverables to session artifacts directory
+7. Write findings to discoveries/{task_id}.json
+8. Report via report_agent_job_result
+
+## Task State
+- tasks.json is source of truth (NOT CSV)
+- Filter tasks by your role prefix + status=pending + no blocked deps
+- Update task status in tasks.json (pending -> in_progress -> completed)
+
+## Inner Loop
+If inner_loop=true, process ALL same-prefix tasks sequentially:
+  Phase 1 -> Phase 2-4 -> Phase 5-L (loop) -> repeat
+  Until no more same-prefix pending tasks -> Phase 5-F (final report)
+
+## Output Schema
+{
+  "id": "<task_id>",
+  "status": "completed | failed",
+  "role": "<role_name>",
+  "findings": "<max 500 chars>",
+  "artifact": "<artifact_path>",
+  "files_modified": [],
+  "error": ""
+}
+
+## Constraints
+- Only process tasks matching your role prefix
+- Never modify tasks outside your scope
+- Report to coordinator only (not other workers)
+- Use CLI tools (ccw cli) or direct tools for exploration
