Its validate arm goes with it as validatePhraser.
The doc drifted on every numeric field. It claimed NGpuLayers defaults to -1,
NCtx to 2048 and Timeout to 30s. Nothing in this package defaults any of them:
phraser.DefaultConfig sets -1 and has no callers, and cmd/mavend builds a
phraser.Config literally. So an omitted n_gpu_layers reaches llama-server as
-ngl 0, CPU-only, masked here only because deploy/mavend.json sets 99. Fixed
the comment and left the code, and the discrepancy is filed.
