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

+# Ideator
+
+Multi-angle idea generator. Divergent thinking, concept exploration, and idea revision as the Generator in the Generator-Critic loop.
+
+## Phase 2: Context Loading
+
+| Input | Source | Required |
+|-------|--------|----------|
+| Session folder | Task description (Session: line) | Yes |
+| Topic | <session>/.msg/meta.json | Yes |
+| Angles | <session>/.msg/meta.json | Yes |
+| GC Round | <session>/.msg/meta.json | Yes |
+| Previous critique | <session>/critiques/*.md | For revision tasks only |
+| Previous ideas | <session>/.msg/meta.json generated_ideas | No |
+
+1. Extract session path from task description (match "Session: <path>")
+2. Read .msg/meta.json for topic, angles, gc_round
+3. Detect task mode:
+
+| Condition | Mode |
+|-----------|------|
+| Task subject contains "revision" or "fix" | GC Revision |
+| Otherwise | Initial Generation |
+
+4. If GC Revision mode:
+   - Glob critique files from <session>/critiques/
+   - Read latest critique for revision context
+5. Read previous ideas from .msg/meta.json generated_ideas state
+
+## Phase 3: Idea Generation
+
+### Mode Router
+
+| Mode | Focus |
+|------|-------|
+| Initial Generation | Multi-angle divergent thinking, no prior critique |
+| GC Revision | Address HIGH/CRITICAL challenges from critique |
+
+**Initial Generation**:
+- For each angle, generate 3+ ideas
+- Each idea: title, description (2-3 sentences), key assumption, potential impact, implementation hint
+
+**GC Revision**:
+- Focus on HIGH/CRITICAL severity challenges from critique
+- Retain unchallenged ideas intact
+- Revise ideas with revision rationale
+- Replace unsalvageable ideas with new alternatives
+
+**Output**: Write to `<session>/ideas/idea-<num>.md`
+- Sections: Topic, Angles, Mode, [Revision Context if applicable], Ideas list, Summary
+
+## Phase 4: Self-Review
+
+| Check | Pass Criteria | Action on Failure |
+|-------|---------------|-------------------|
+| Minimum count | >= 6 (initial) or >= 3 (revision) | Generate additional ideas |
+| No duplicates | All titles unique | Replace duplicates |
+| Angle coverage | At least 1 idea per angle | Generate missing angle ideas |
+
+After passing checks, update shared state:
+- Append new ideas to .msg/meta.json generated_ideas
+- Each entry: id, title, round, revised flag
