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

+# General UX Principles
+
+## Feedback & Responsiveness
+- Every user action should have immediate visual feedback
+- Loading states must be shown for operations >200ms
+- Success/error states should be clearly communicated
+
+## State Management
+- UI state should reflect the underlying data state
+- Optimistic updates should have rollback mechanisms
+- State changes should be atomic and predictable
+
+## Accessibility
+- Interactive elements must be keyboard accessible
+- Color should not be the only indicator of state
+- Focus states must be visible
