Detailed Description

Abstract Sampler seam for backend testability (v2.3.10).

Pre-v2.3.10 LlamaCppBackend built its llama_sampler_chain inline from GenerationParams and invoked llama_sampler_sample directly in the decode loop. Every line of chain construction was therefore unreachable under the CPU-only unit-test coverage gate (no real model, no real context). This abstract seam relocates chain construction behind a SamplerFactory and relocates per-token sampling behind a Sampler — both mockable. The production backend wires LlamaCppSamplerFactory (which builds the real llama.cpp chain); unit tests inject a mock factory + mock sampler and assert behavior without a loaded model.

Pairs structurally with the v2.3.10 Tokenizer seam (see tokenizer.h).
