feat(transport): Phase 2 fetch protocol — single presigned URL, sha256 integrity gate

Replace the three old fetch branches (pack_fetch multi-URL, presign flag, inline bytes) with the single Phase 2 shape: server returns {mpack_url, mpack_id, commit_count, object_count}. Client GETs mpack_url directly, verifies blob_id(bytes) == mpack_id before unpacking, raises TransportError on mismatch or non-200. Null mpack_url = up-to-date, returns empty result.

Adds TDD suite (FM-1 through FM-6) — all 6 pass. Removes unused hashlib import; adds blob_id to types import.
