Detailed Description

Default schema plugin implementation built around linked protobuf metadata and embedded BFBS blobs.

SchemaPluginBase intentionally keeps the protobuf side aligned with the previous protobuf-only runtime behaviour:

• protobuf descriptors are resolved directly from google::protobuf::DescriptorPool::generated_pool()
• protobuf schema payloads are serialised from the linked FileDescriptor graph
• dynamic protobuf messages are created via DynamicMessageFactory

FlatBuffers differs because there is no global descriptor pool. Therefore the concrete plugin/library must explicitly register compiled-in BFBS blobs into the process-local FlatbuffersRegistry through FlatbuffersRegistry::register_schema() or the convenience macro VLINK_REGISTER_FLATBUFFERS. A common pattern is to generate headers with flatc –bfbs-gen-embed and register the emitted *BinarySchema helpers at translation-unit scope inside the plugin/library.

This base class does not read VLINK_PROTO_DIR, VLINK_FBS_DIR, or any schema files from the file system.
