📄 Description

pickBestPartialFitByLibrary() sets numParallel = 1, but doesn't adjust req.opts.NumCtx. If OLLAMA_NUM_PARALLEL has been set, NumCtx = OLLAMA_NUM_PARALLEL * defaultParallel. Unconditionally setting numParallel to 1 causes problems in needsReload() - because NumCtx hasn't been reset, !reflect.DeepEqual(optsExisting, optsNew) always fails, causing the model to be reloaded for every request.

It's not clear why numParallel is forced to 1, testing indicates that models operate normally with a partial load and parallelism, so this PR changes the code to set numParallel and req.opts.NumCtx only if unset.
