feat(claw-eval): add gen_ai.provider.name to invoke_agent_internal span

Add _infer_provider_name() helper to resolve provider name from the
provider instance. This fixes a P0 compliance gap where the Required
attribute gen_ai.provider.name was missing on invoke_agent_internal
spans in the CLAW-eval instrumentation.
