fix: propagate removeBodyFields in treatAsLocal path

The treatAsLocal code path was dropping removeBodyFields from the
model-inference config. For DeepSeek/Kimi models, inference returns
removeBodyFields: ['store'] which was silently lost for local proxies.

Currently mitigated by the isLocal store-stripping check, but this
ensures future removeBodyFields entries are also preserved.
