- Implement `test-cli-command-gen.js` to verify the logic of `buildCliCommand` function.
- Create `test-e2e-model-alias.js` for end-to-end testing of model alias resolution in `ccw cli`.
- Add `test-model-alias.js` to test model alias resolution for different models.
- Introduce `test-model-alias.txt` for prompt testing with model alias.
- Develop `test-update-claude-command.js` to test command generation for `update_module_claude`.
- Create a test file in `test-update-claude/src` for future tests.
