Migrate files API call sites from sdk.files.* (Stainless SDK) to client_from_platform(sdk, FilesClient).* (typed HTTP client), following the pattern established in #1277. Changes across 20 files: - upload_content(content=..., remote_path=..., fileset=...) -> upload_file(name=..., path=..., content=...) - download_content(remote_path=..., fileset=...) -> download_file(name=..., path=...) - list(fileset=..., workspace=...) -> list_files(name=..., workspace=..., query_params=ListFilesQueryParams(...)) - delete(...) -> delete_file(...) - filesets.create(name=...) -> create_fileset(body=CreateFilesetRequest(name=...)) - filesets.retrieve/delete -> get_fileset/delete_fileset 2 files skipped (evaluate_agent.py, fileset_io.py): the old sdk.files.download() downloads a fileset tree to a directory, while the new download_file() downloads a single file and returns BinaryContent. These need special handling during/after the spine flip. 5 files skipped (auto-generated CLI, extended FilesResource, docstring-only references): left for CLI generator update.

Use the typed single-file download contract at all affected call sites.
FilesClient.download_file accepts one path together with workspace and name, returns the file bytes, and does not accept local_path or download an entire fileset. Obtain the required paths with list_files where needed, download each file separately, and write it to the destination while preserving relative and nested paths. Apply the same pattern in e2e/files/test_files.py and services/core/files/tests/integration/external_storage/test_huggingface_storage.py.

Send the Range header in all partial-download tests.
FilesClient.download_file sends no Range header. The service returns the full file with 200 when the header is absent, so these assertions can fail at status_code == 206 and payload length.

Use the header-capable _download_file operation with extra_headers={"Range": ...}.

Keep FilesClient instances separate from list data.
.data() returns the file sequence. These sites later call client methods on that sequence or access a nonexistent .data field.

Use the typed upload_file argument names.
FilesClient.upload_file accepts path and name, not remote_path and fileset. These calls can raise an unexpected-keyword error before the IAM assertions run. Replace both calls with path="a.txt" and the corresponding fileset as name.
