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

+# Pipeline Definitions — team-brainstorm
+
+## Available Pipelines
+
+### Quick Pipeline (3 beats, strictly serial)
+
+```
+IDEA-001 → CHALLENGE-001 → SYNTH-001
+[ideator]   [challenger]   [synthesizer]
+```
+
+### Deep Pipeline (6 beats, Generator-Critic loop)
+
+```
+IDEA-001 → CHALLENGE-001 → IDEA-002(fix) → CHALLENGE-002 → SYNTH-001 → EVAL-001
+```
+
+GC loop check: if critique.severity >= HIGH → create IDEA-fix → CHALLENGE-2 → SYNTH; else skip to SYNTH
+
+### Full Pipeline (7 tasks, fan-out parallel ideation + GC)
+
+```
+[IDEA-001 + IDEA-002 + IDEA-003](parallel) → CHALLENGE-001(batch) → IDEA-004(fix) → SYNTH-001 → EVAL-001
+```
+
+## Task Metadata Registry
+
+| Task ID | Role | Phase | Dependencies | Description |
+|---------|------|-------|-------------|-------------|
+| IDEA-001 | ideator | generate | (none) | Multi-angle idea generation |
+| IDEA-002 | ideator | generate | (none) | Parallel angle (Full pipeline only) |
+| IDEA-003 | ideator | generate | (none) | Parallel angle (Full pipeline only) |
+| CHALLENGE-001 | challenger | challenge | IDEA-001 (or all IDEA-*) | Devil's advocate critique and feasibility challenge |
+| IDEA-004 | ideator | gc-fix | CHALLENGE-001 | Revision based on critique (GC loop, if triggered) |
+| CHALLENGE-002 | challenger | gc-fix | IDEA-004 | Re-critique of revised ideas (GC loop round 2) |
+| SYNTH-001 | synthesizer | synthesize | last CHALLENGE-* | Cross-idea integration, theme extraction, conflict resolution |
+| EVAL-001 | evaluator | evaluate | SYNTH-001 | Scoring, ranking, priority recommendation, final selection |
+
+## Checkpoints
+
+| Trigger | Location | Behavior |
+|---------|----------|----------|
+| Generator-Critic loop | After CHALLENGE-* | If severity >= HIGH → create IDEA-fix task; else proceed to SYNTH |
+| GC loop limit | Max 2 rounds | Exceeds limit → force convergence to SYNTH |
+| Pipeline stall | No ready + no running | Check missing tasks, report to user |
+
+## Completion Conditions
+
+| Mode | Completion Condition |
+|------|---------------------|
+| quick | All 3 tasks completed |
+| deep | All 6 tasks (+ any skipped GC tasks) completed |
+| full | All 7 tasks (+ any skipped GC tasks) completed |
