v0.2.0

• Added BaseSchemaModel base class with unified serialization (to_dict, from_dict, to_json, from_json) and optional proto support via __proto_message__
• Added -> Self return type annotations on BaseSchemaModel classmethods (from_dict, from_json, from_proto)
• Added create_callbacks_from_config() utility for training callback instantiation (with guarded pytorch_lightning import)
• Added Context.to_dict() / Context.from_dict() and plugin serialization helpers
• Added buf.yaml and buf.gen.yaml for proto stub generation via buf
• Added breaking/lint rules to buf config
• Changed proto source location from proto/cuvis_ai/ to proto/cuvis_ai_schemas/ to match Python package namespace

• Changed NodeConfig: renamed id → name, params → hparams, dropped class alias (now class_name only)
• Changed ConnectionConfig: replaced from_node/from_port/to_node/to_port fields with compact source/target dotted-path format ("node.outputs.port")
• Changed PipelineConfig to fully typed Pydantic model with JSON-safe save_to_file serialization
• Fixed Pipelinees typo in proto source — renamed to Pipelines (message types, field names, and RPC method)
