fix(transport): convert SnapshotDict→delta in push_stream; use delta_add in fetch_stream

LocalFileTransport.push_stream passed SnapshotDict (manifest key) directly into MPackBundle.snapshots, but apply_mpack/_apply_snapshot_deltas only understands SnapshotDeltaDict (delta_add/delta_remove). Snapshots were never written to the remote after a local push, so subsequent pulls saw missing snapshots and excluded the commits from the pack.

fetch_stream also collected object IDs from snap.get('manifest') but build_mpack produces SnapshotDeltaDict entries, so all_oids was always empty and on_object was never called — objects were not dispatched to the pull caller.

Both bugs together caused test_pull_fetches_commit_and_objects to fail with exit_code=1 (pull aborted: commit not readable after apply).
