Review Comment:
There’s a new branch that updates Blob headers when `contentMd5 != null`,
but the added tests only cover the `upload(...)` call. Add a unit test that
enables checksum/MD5 generation (so `contentMd5` is non-null) and verifies the
Blob path calls `setHttpHeaders(...)` with the expected MD5.
