… SDKs Adds a module-level registry in create_resource_attributes_from_env() so companion SDKs (e.g. sap-internal-sdk) can contribute their version as an OTel resource attribute at import time, without requiring any change to agent startup code.
Remove the import-time registry (_extra_sdk_attributes / register_sdk_resource_attributes) and replace it with importlib.metadata entry_points discovery at auto_instrument() call time. Any installed package that registers a callable under the "sap_cloud_sdk.resource_providers" group has its returned dict merged into the resource attributes automatically — no import order dependency, no agent code change required.
