Function store_file_object 

pub fn store_file_object(
    store: &ObjectStore,
    data: &[u8],
) -> WorktreeResult<Hash>

Store a regular file’s bytes as the canonical object and return its content-address.

This is the single source of truth for how file content maps to an object hash, shared by hash_file, build_tree, and mkit add so all three agree on the representation:

• At or below CHUNK_THRESHOLD: a single Blob.
• Above the threshold: FastCdc::v1 chunks, each stored as a Blob, addressed by a ChunkedBlob manifest.
