Two tiny Go-side changes that let the llama/compat shim take over gemma3:
1. llm/llama_server.go: when the GGUF has embedded v.* tensors and no
projector layer is declared, pass the model file itself as --mmproj.
The in-process compat layer translates the same file into both a
text-only view (for --model) and a clip-mmproj view (for --mmproj).
2. server/model_resolver.go: drop library/gemma3 from compatModelRedirects.
The compat layer handles it directly, so no dhiltgen/ republish is
needed. Other arches stay in the redirect list until they get their
own handler in llama/compat/llama-ollama-compat.cpp.
End-to-end verified: `ollama run gemma3` answers text and image prompts
against the existing library/gemma3 blob with no re-download.
