Summary: PR https://github.com/facebook/rocksdb/issues/14266 ("Remove compression support") removed compression-related functionality from blob_dump_tool and ldb commands. While this was valid for the legacy stacked BlobDB (which no longer supports compression), the integrated blob storage (`enable_blob_files`) uses the same blob file format and fully supports compression via `blob_compression_type`. This partial revert restores the ability to view uncompressed blob data from compressed blob files, which is essential for debugging and analysis of integrated blob storage. Restored functionality: - `blob_dump --show_uncompressed_blob` option - `ldb dump --dump_uncompressed_blobs` option - `ldb dump_live_files --dump_uncompressed_blobs` option - Related ldb_test.py test coverage The decompression implementation in utilities/blob_db/blob_dump_tool.cc has been updated to use the modern `GetBuiltinV2CompressionManager()->GetDecompressorOptimizeFor()` API. Suggested follow-up: * Tests for blob_dump (or integrate it into sst_dump/ldb?)
