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-issue
+
+## Available Pipelines
+
+### Quick Pipeline (4 beats, strictly serial)
+
+```
+EXPLORE-001 → SOLVE-001 → MARSHAL-001 → BUILD-001
+[explorer]    [planner]   [integrator]  [implementer]
+```
+
+Use when: 1-2 simple issues, no high-priority (priority < 4).
+
+### Full Pipeline (5 beats, with review gate)
+
+```
+EXPLORE-001 → SOLVE-001 → AUDIT-001 ─┬─(approved/concerns)→ MARSHAL-001 → BUILD-001
+[explorer]    [planner]   [reviewer]  │
+                                      └─(rejected, round<2)→ SOLVE-fix-001 → AUDIT-002 → MARSHAL-001 → BUILD-001
+```
+
+Use when: 1-4 issues with high-priority, or 3-4 issues regardless of priority.
+
+### Batch Pipeline (parallel windows)
+
+```
+[EXPLORE-001..N](parallel, max 5) → [SOLVE-001..N](sequential) → AUDIT-001 → MARSHAL-001 → [BUILD-001..M](parallel, max 3, deferred)
+```
+
+Use when: 5+ issues.
+
+Note: BUILD tasks are created dynamically after MARSHAL completes and execution-queue.json is available.
+
+## Task Metadata Registry
+
+| Task ID | Role | Phase | Dependencies | Description |
+|---------|------|-------|-------------|-------------|
+| EXPLORE-001 | explorer | explore | (none) | Context analysis and impact assessment |
+| EXPLORE-002..N | explorer | explore | (none) | Parallel exploration (Batch mode only, max 5) |
+| SOLVE-001 | planner | plan | EXPLORE-001 (or all EXPLORE-*) | Solution design and task decomposition |
+| SOLVE-002..N | planner | plan | all EXPLORE-* | Parallel solution design (Batch mode only) |
+| AUDIT-001 | reviewer | review | SOLVE-001 (or all SOLVE-*) | Technical feasibility and risk review (Full/Batch) |
+| SOLVE-fix-001 | planner | fix | AUDIT-001 | Revised solution addressing reviewer feedback |
+| AUDIT-002 | reviewer | re-review | SOLVE-fix-001 | Re-review of revised solution |
+| MARSHAL-001 | integrator | integrate | AUDIT-001 (or last SOLVE-* in quick) | Conflict detection and queue orchestration |
+| BUILD-001 | implementer | implement | MARSHAL-001 | Code implementation and result submission |
+| BUILD-002..M | implementer | implement | MARSHAL-001 | Parallel implementation (Batch, deferred creation) |
+
+## Mode Auto-Detection
+
+| Condition | Mode |
+|-----------|------|
+| User specifies `--mode=<M>` | Use specified mode |
+| Issue count <= 2 AND no high-priority (priority < 4) | `quick` |
+| Issue count <= 2 AND has high-priority (priority >= 4) | `full` |
+| 3-4 issues | `full` |
+| Issue count >= 5 | `batch` |
+
+## Checkpoints
+
+| Trigger | Location | Behavior |
+|---------|----------|----------|
+| Review gate | After AUDIT-* | approved/concerns → MARSHAL; rejected → SOLVE-fix (max 2 rounds) |
+| Review loop limit | fix_cycles >= 2 | Force proceed to MARSHAL with warnings |
+| Deferred BUILD creation | After MARSHAL-* (batch) | Read execution-queue.json, create BUILD tasks |
+| Pipeline stall | No ready + no running | Check missing tasks, report to user |
+
+## Completion Conditions
+
+| Mode | Completion Condition |
+|------|---------------------|
+| quick | All 4 tasks completed |
+| full | All 5 tasks (+ any fix cycle tasks) completed |
+| batch | All N EXPLORE + N SOLVE + 1 AUDIT + 1 MARSHAL + M BUILD (+ any fix cycle tasks) completed |
+
+## Parallel Spawn Rules
+
+| Pipeline | Stage | Max Parallel |
+|----------|-------|-------------|
+| Batch | EXPLORE-001..N | min(N, 5) |
+| Batch | BUILD-001..M | min(M, 3) |
+| All | All other stages | 1 |
+
+## Shared State (meta.json)
+
+| Role | State Key |
+|------|-----------| 
+| explorer | `explorer` (issue_id, complexity, impact_scope, file_count) |
+| planner | `planner` (issue_id, solution_id, task_count, is_revision) |
+| reviewer | `reviewer` (overall_verdict, review_count, scores) |
+| integrator | `integrator` (queue_size, parallel_groups, conflict_count) |
+| implementer | `implementer` (issue_id, executor, test_status, review_status) |
+
+## Message Types
+
+| Role | Types |
+|------|-------|
+| coordinator | `pipeline_selected`, `review_result`, `fix_required`, `task_unblocked`, `error`, `shutdown` |
+| explorer | `context_ready`, `error` |
+| planner | `solution_ready`, `multi_solution`, `error` |
+| reviewer | `approved`, `concerns`, `rejected`, `error` |
+| integrator | `queue_ready`, `conflict_found`, `error` |
+| implementer | `impl_complete`, `impl_failed`, `error` |
+
+## Review-Fix Cycle
+
+```
+AUDIT verdict: rejected
+    │
+    ├─ fix_cycles < 2 → create SOLVE-fix-<N> + AUDIT-<N+1> → spawn planner → wait
+    │                       ↑
+    │                   (repeat if rejected again)
+    │
+    └─ fix_cycles >= 2 → force proceed to MARSHAL with rejection warning logged
+```
+
+## Deferred BUILD Creation (Batch Mode)
+
+BUILD tasks are not created during initial dispatch. After MARSHAL-001 completes:
+1. Read `.workflow/issues/queue/execution-queue.json`
+2. Parse `parallel_groups` to determine M
+3. Create BUILD-001..M tasks with `addBlockedBy: ["MARSHAL-001"]`
+4. Assign owners: M <= 2 → "implementer"; M > 2 → "implementer-1".."implementer-M" (max 3)
+5. Spawn implementer workers via handleSpawnNext
