### Describe the Bug

`wrangler r2 object get --remote` appears to return stale data for object keys ending with `.zst`.

For keys without that extension, such as `file1` and `file2.txt`, overwrites and deletes are reflected correctly.

For a `.zst` key such as `file3.zst`:

- after overwriting the object with `wrangler r2 object put --remote`, `wrangler r2 object get --remote` still returns the old content
- after deleting the object with `wrangler r2 object delete --remote`, `wrangler r2 object get --remote` still returns the old content
- the same key accessed through the S3-compatible API (`aws s3 cp`) shows the correct latest state, and returns 404 after deletion

In my reproduction, `wrangler r2 object get --remote` continues to return stale data for `file3.zst` even after the bucket itself has been deleted.

Expected behavior:
- `wrangler r2 object get --remote` should return the latest contents after overwrite
- it should return `The specified key does not exist.` after delete
- behavior should not depend on the file extension
