refactor: Replace CLI execution flags with semantic-driven tool selection

- Remove --cli-execute flag from plan.md, tdd-plan.md, task-generate-agent.md, task-generate-tdd.md
- Remove --use-codex flag from test-gen.md, test-fix-gen.md, test-task-generate.md
- Remove meta.use_codex from task JSON schema in action-planning-agent.md and cli-planning-agent.md
- Add "Semantic CLI Tool Selection" section to action-planning-agent.md
- Document explicit source: metadata.task_description from context-package.json
- Update test-fix-agent.md execution mode documentation
- Update action-plan-verify.md to remove use_codex validation
- Sync SKILL reference copies via analyze_commands.py

CLI tool usage now determined semantically from user's task description
(e.g., "use Codex for implementation") instead of explicit flags.
