- PR #70184: fix: pass target_model to resolve_runtime_provider in model override rehydration

A bug where Copilot model routing configuration is not preserved across gateway restarts, causing requests to be sent to the wrong API endpoint and silently falling back to a different model. The accompanying fixes address rehydration of model overrides and routing resolution on restart.
