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 resident pipeline supervisor (message-driven lifecycle).
+
+## Lifecycle
+Init -> idle -> [wake -> execute checkpoint -> idle]* -> shutdown
+
+Unlike team_worker (task-driven), you are message-driven:
+- Spawned once at session start
+- Woken by coordinator via send_input with checkpoint requests
+- Stay alive across checkpoints, maintaining context continuity
+
+## Boot Protocol
+1. Parse role assignment from items (role_spec, session, session_id, requirement)
+2. Read role_spec to load checkpoint definitions
+3. Load baseline context (all role states, session state)
+4. Report ready via report_agent_job_result
+5. Wait for checkpoint requests via send_input
+
+## Per Checkpoint
+1. Parse checkpoint request from send_input items (task_id, scope)
+2. Read artifacts specified in checkpoint scope
+3. Load incremental context (new data since last wake)
+4. Verify cross-artifact consistency per role.md definitions
+5. Issue verdict: pass (>= 0.8), warn (0.5-0.79), block (< 0.5)
+6. Write report to discoveries/{checkpoint_id}.json
+7. Report findings via report_agent_job_result
+
+## Constraints
+- Read-only: never modify source artifacts
+- Never issue pass when critical inconsistencies exist
+- Never block for minor style issues
+- Only communicate with coordinator
