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

+# Tech Debt Assessor
+
+Quantitative evaluator for tech debt items. Score each debt item on business impact (1-5) and fix cost (1-5), classify into priority quadrants, produce priority-matrix.json.
+
+## Phase 2: Load Debt Inventory
+
+| Input | Source | Required |
+|-------|--------|----------|
+| Session path | task description (regex: `session:\s*(.+)`) | Yes |
+| .msg/meta.json | <session>/.msg/meta.json | Yes |
+| Debt inventory | meta.json:debt_inventory OR <session>/scan/debt-inventory.json | Yes |
+
+1. Extract session path from task description
+2. Read .msg/meta.json for team context
+3. Load debt_inventory from shared memory or fallback to debt-inventory.json file
+4. If debt_inventory is empty -> report empty assessment and exit
+
+## Phase 3: Evaluate Each Item
+
+**Strategy selection**:
+
+| Item Count | Strategy |
+|------------|----------|
+| <= 10 | Heuristic: severity-based impact + effort-based cost |
+| 11-50 | CLI batch: single gemini analysis call |
+| > 50 | CLI chunked: batches of 25 items |
+
+**Impact Score Mapping** (heuristic):
+
+| Severity | Impact Score |
+|----------|-------------|
+| critical | 5 |
+| high | 4 |
+| medium | 3 |
+| low | 1 |
+
+**Cost Score Mapping** (heuristic):
+
+| Estimated Effort | Cost Score |
+|------------------|------------|
+| small | 1 |
+| medium | 3 |
+| large | 5 |
+| unknown | 3 |
+
+**Priority Quadrant Classification**:
+
+| Impact | Cost | Quadrant |
+|--------|------|----------|
+| >= 4 | <= 2 | quick-win |
+| >= 4 | >= 3 | strategic |
+| <= 3 | <= 2 | backlog |
+| <= 3 | >= 3 | defer |
+
+For CLI mode, prompt gemini with full debt summary requesting JSON array of `{id, impact_score, cost_score, risk_if_unfixed, priority_quadrant}`. Unevaluated items fall back to heuristic scoring.
+
+## Phase 4: Generate Priority Matrix
+
+1. Build matrix structure: evaluation_date, total_items, by_quadrant (grouped), summary (counts per quadrant)
+2. Sort within each quadrant by impact_score descending
+3. Write `<session>/assessment/priority-matrix.json`
+4. Update .msg/meta.json with `priority_matrix` summary and evaluated `debt_inventory`
