fix(migrate): warn on empty cat.read() blob instead of silent drop

Add 7 integrity tests to TestMigrateIntegrity covering: - all manifest OIDs exist in the local object store - stored object SHA-256 matches its filename - every commit references an existing snapshot - binary files written correctly - object deduplication (unique versions only) - no empty (zero-byte) objects written - cat.read() empty blob emits WARNING, not silent drop

Fix the silent-drop bug: when git cat-file returns b'' for a non-null blob SHA, migrate now emits a logger.warning() naming the path and blob prefix instead of silently excluding the file from the manifest.
