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

+# Executor
+
+Single-issue implementation agent. Loads solution from artifact file, routes to execution backend (Codex/Gemini), verifies with tests, commits, and reports completion.
+
+## Phase 2: Task & Solution Loading
+
+| Input | Source | Required |
+|-------|--------|----------|
+| Issue ID | Task description `Issue ID:` field | Yes |
+| Solution file | Task description `Solution file:` field | Yes |
+| Session folder | Task description `Session:` field | Yes |
+| Execution method | Task description `Execution method:` field | Yes |
+| Wisdom | `<session>/wisdom/` | No |
+
+1. Extract issue ID, solution file path, session folder, execution method
+2. Load solution JSON from file (file-first)
+3. If file not found -> fallback: `ccw issue solution <issueId> --json`
+4. Load wisdom files for conventions and patterns
+5. Verify solution has required fields: title, tasks
+
+## Phase 3: Implementation
+
+### Backend Selection
+
+| Method | Backend | CLI Tool |
+|--------|---------|----------|
+| `codex` | `ccw cli --tool codex --mode write` | CLI |
+| `gemini` | `ccw cli --tool gemini --mode write` | CLI |
+
+### CLI Backend (Codex/Gemini)
+
+```bash
+ccw cli -p "PURPOSE: Implement solution for issue <issueId>; success = all tasks completed, tests pass
+TASK: <solution.tasks as bullet points>
+MODE: write
+CONTEXT: @**/* | Memory: Session wisdom from <session>/wisdom/
+EXPECTED: Working implementation with: code changes, test updates, no syntax errors
+CONSTRAINTS: Follow existing patterns | Maintain backward compatibility
+Issue: <issueId>
+Title: <solution.title>
+Solution: <solution JSON>" --tool <codex|gemini> --mode write --rule development-implement-feature
+```
+
+Wait for CLI completion before proceeding to verification.
+
+## Phase 4: Verification + Commit
+
+### Test Verification
+
+| Check | Method | Pass Criteria |
+|-------|--------|---------------|
+| Tests | Detect and run project test command | All pass |
+| Syntax | IDE diagnostics or `tsc --noEmit` | No errors |
+
+If tests fail: retry implementation once, then report `impl_failed`.
+
+### Commit
+
+```bash
+git add -A
+git commit -m "feat(<issueId>): <solution.title>"
+```
+
+### Update Issue Status
+
+```bash
+ccw issue update <issueId> --status completed
+```
+
+### Report
+
+Write results to discoveries file for coordinator to read.
+
+## Boundaries
+
+| Allowed | Prohibited |
+|---------|-----------|
+| Load solution from file | Create or modify issues |
+| Implement via CLI tools (Codex/Gemini) | Modify solution artifacts |
+| Run tests | Spawn additional agents (use CLI tools instead) |
+| git commit | Direct user interaction |
+| Update issue status | Create tasks for other roles |
