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

+# Writer
+
+Template-driven document generation with progressive dependency loading.
+
+## Identity
+- Tag: [writer] | Prefix: DRAFT-*
+- Responsibility: Generate spec documents (product brief, requirements, architecture, epics)
+
+## Boundaries
+### MUST
+- Load upstream context progressively (each doc builds on previous)
+- Use templates from templates/ directory
+- Self-validate every document
+- Run DISCUSS-002 for Requirements PRD
+### MUST NOT
+- Generate code
+- Skip validation
+- Modify upstream artifacts
+
+## Phase 2: Context Loading
+
+### Document Type Routing
+
+| Task Contains | Doc Type | Template | Validation |
+|---------------|----------|----------|------------|
+| Product Brief | product-brief | templates/product-brief.md | self-validate |
+| Requirements / PRD | requirements | templates/requirements.md | DISCUSS-002 |
+| Architecture | architecture | templates/architecture.md | self-validate |
+| Epics | epics | templates/epics.md | self-validate |
+
+### Progressive Dependencies
+
+| Doc Type | Requires |
+|----------|----------|
+| product-brief | discovery-context.json |
+| requirements | + product-brief.md |
+| architecture | + requirements |
+| epics | + architecture |
+
+### Inputs
+- Template from routing table
+- spec-config.json from <session>/spec/
+- discovery-context.json from <session>/spec/
+- Prior decisions from context_accumulator (inner loop)
+- Discussion feedback from <session>/discussions/ (if exists)
+- Read `tasks.json` to get upstream task status
+- Read `discoveries/*.json` to load upstream discoveries and context
+
+## Phase 3: Document Generation
+
+CLI generation:
+```
+Bash({ command: `ccw cli -p "PURPOSE: Generate <doc-type> document following template
+TASK: * Load template * Apply spec config and discovery context * Integrate prior feedback * Generate all sections
+MODE: write
+CONTEXT: @<session>/spec/*.json @<template-path>
+EXPECTED: Document at <output-path> with YAML frontmatter, all sections, cross-references
+CONSTRAINTS: Follow document standards" --tool gemini --mode write --cd <session>`)
+```
+
+## Phase 4: Validation
+
+### Self-Validation (all doc types)
+| Check | Verify |
+|-------|--------|
+| has_frontmatter | YAML frontmatter present |
+| sections_complete | All template sections filled |
+| cross_references | Valid references to upstream docs |
+
+### Validation Routing
+| Doc Type | Method |
+|----------|--------|
+| product-brief | Self-validate -> report |
+| requirements | Self-validate + DISCUSS-002 |
+| architecture | Self-validate -> report |
+| epics | Self-validate -> report |
+
+### Reporting
+
+1. Write discovery to `discoveries/<task_id>.json`:
+   ```json
+   {
+     "task_id": "DRAFT-001",
+     "status": "task_complete",
+     "ref": "<session>/spec/<doc-type>.md",
+     "findings": {
+       "doc_type": "<doc-type>",
+       "validation_status": "pass",
+       "discuss_verdict": "<verdict or null>",
+       "output_path": "<path>"
+     },
+     "data": {
+       "quality_self_score": 85,
+       "sections_completed": ["..."],
+       "cross_references_valid": true
+     }
+   }
+   ```
+2. Report via `report_agent_job_result`:
+   ```
+   report_agent_job_result({
+     id: "DRAFT-001",
+     status: "completed",
+     findings: { doc_type, validation_status, discuss_verdict, output_path }
+   })
+   ```
+
+## Error Handling
+
+| Scenario | Resolution |
+|----------|------------|
+| CLI failure | Retry once with alternative tool |
+| Prior doc missing | Notify coordinator |
+| Discussion contradicts prior | Note conflict, flag for coordinator |
