haylanandClaude-Bot c5864beec9 feat(llama.cpp): raise default context to 128K, document RAM/SSD offload knobs
LLAMA_CTX_SIZE default 65536 -> 131072: real usage was burning through 64K
fast. ~25.6GB VRAM (17.6GB weights + ~8GB KV cache) on the 32GB R9700,
~6GB headroom — see docs/research/qwen3.8-27b-quant.md for the full table.

Also documents LLAMA_GPU_LAYERS as the RAM-offload knob for this dense
model (no separate RAM-offload flag exists in llama.cpp, and --n-cpu-moe/
--cpu-moe/--override-tensor "exps" are MoE-only, no-ops here), and that
there's no explicit SSD offload tier to enable — llama.cpp's default mmap
already falls back to disk implicitly if GPU+RAM run out.

# 999 = every layer on GPU (this model is dense, not MoE, and already fits
# fully in 32GB VRAM — see docs/research/qwen3.8-27b-quant.md). Lower this
# to leave that many fewer layers on GPU and push the rest to CPU/system RAM
# if something else is contending for VRAM — llama.cpp has no separate
# "RAM offload" flag, --n-gpu-layers *is* the RAM-offload knob for a dense
# model. Don't reach for --n-cpu-moe/--cpu-moe/--override-tensor "exps" —
# those target Mixture-of-Experts models (e.g. Qwen3.8-2.4T-A95B), not this
# one, and are no-ops here.
# There's no separate "then SSD" tier to enable either: llama.cpp mmaps the
# model file by default (no --no-mmap here), so if GPU+RAM ever can't hold
# the working set, the OS pages the rest in from disk automatically — an
# implicit, slow last resort, not a config knob. An explicit tiered SSD
# offload has been an open llama.cpp feature request since 2025 (still
# unimplemented): https://github.com/ggml-org/llama.cpp/discussions/12507
