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

+# Implement
+
+Execute implementation from task JSON via agent or CLI delegation.
+
+## Agent Mode
+
+Direct implementation using Edit/Write/Bash tools:
+
+1. Read task.files[] as target files
+2. Read task.implementation[] as step-by-step instructions
+3. For each step:
+   - Substitute [variable] placeholders with pre_analysis results
+   - New file -> Write tool; Modify file -> Edit tool
+   - Follow task.reference patterns
+4. Apply task.rationale.chosen_approach
+5. Mitigate task.risks[] during implementation
+
+Quality rules:
+- Verify module existence before referencing
+- Incremental progress -- small working changes
+- Follow existing patterns from task.reference
+- ASCII-only, no premature abstractions
+
+## CLI Delegation Mode
+
+Build prompt from task JSON, delegate to CLI:
+
+Prompt structure:
+```
+PURPOSE: <task.title>
+<task.description>
+
+TARGET FILES:
+<task.files[] with paths and changes>
+
+IMPLEMENTATION STEPS:
+<task.implementation[] numbered>
+
+PRE-ANALYSIS CONTEXT:
+<pre_analysis results>
+
+REFERENCE:
+<task.reference pattern and files>
+
+DONE WHEN:
+<task.convergence.criteria[]>
+
+MODE: write
+CONSTRAINTS: Only modify listed files | Follow existing patterns
+```
+
+CLI call:
+```
+Bash(`ccw cli -p "<prompt>" --tool <tool> --mode write --rule development-implement-feature`)
+```
+
+Resume strategy:
+| Strategy | Command |
+|----------|---------|
+| new | --id <session>-<task_id> |
+| resume | --resume <parent_id> |
+
+RoleSpec: `.codex/skills/team-lifecycle-v4/roles/executor/role.md`
