feat: fetch_bundle on HttpTransport and LocalFileTransport (issue #47)

Add fetch_bundle(url, signing, want, have, *, on_object, ttl_seconds) to both transport classes and the MuseTransport Protocol.

HttpTransport: - POST /fetch/bundle → msgpack FetchBundleResult - presign=False: bundle bytes inline - presign=True: GET presigned_url for bundle bytes - sha256(bytes) == bundle_id verified before unpack — one hash, all contents - on_object callback dispatched for each object in the bundle - Non-200 from POST or presigned GET → TransportError - Integrity mismatch → TransportError

LocalFileTransport: - Delegates to fetch_stream unconditionally (no presign on loopback)

8 TDD tests (FB0-FB7): inline path, sha256 mismatch, presigned path, presigned mismatch, on_object callback, POST 404, GET 403, local delegate.
