Add client.files namespace for file upload operations

- Create FileOperations class with upload() method in operations/files.py
- Deprecate client.upload_file() with DeprecationWarning pointing to
  client.files.upload()
- Update file_upload example, README, and both SKILL files
- Add namespace delegation tests and deprecation test
