Viktor Barzin 6e7fe96a40 infra/llama-cpp: benchmark report + -fa flag fix
Phase 7 of the vision-LLM benchmark plan. Adds:

- docs/benchmarks/2026-05-10-vision-llm.md — curated report (TL;DR,
  per-model analysis, top-N agreement, cost vs cloud APIs, sample
  captions). Verdict: qwen3vl-4b for the request path (3.55 s p50,
  100% parse, decisive top-N distro); qwen3vl-8b for caption polish.
- docs/benchmarks/benchmark-2026-05-10-1424.json — raw 300-row dump
  for diff-checking against future runs.
- main.tf: -fa -> -fa on (b9085 llama.cpp removed the no-value form
  of the flash-attention flag; without the value llama-server exits
  before serving any request).
- llama-cpp.md architecture doc links the report so future operators
  land on the deployed-and-evaluated model from one entry point.

300/300 calls, 0 parse errors, 33m32s wall on a single T4 with the
GPU exclusively allocated. immich-ml was scaled to 0 for the run
(node1 RAM constraint, not GPU - bumping node1 RAM is tracked as a
follow-up).
