llama.cpp b10273: Sampler Context Size Change

In version b10273 of llama.cpp, the default context size for history-based samplers has been standardized at 64. This change resolves an earlier issue where samplers were initialized before the complete llama_context was available, leading to uncertainty about the resolved context length. The removal of 'full-context windows' from these samplers ensures more consistent behavior across different contexts and deployments. Local AI operators should be aware that this update could affect how historical data is sampled in their models, potentially impacting performance or output quality.
