chore(ai): refactor duplicated copying logic in src/ops.mjs

- Extracted `syncAppDirectories` and `syncAppFiles` helper functions.
- Updated `cmdInit` and `cmdUpdate` to use the new helpers.
- Improved `cmdInit` to throw an Error instead of warning when the target directory is not empty and not forced.
- Fixed hanging tests in `test/ops.test.mjs` by providing `MOCK_CONFIG`.
- Updated tests to verify strict directory check in `cmdInit`.
