teknium1 75317d82d0 fix(vision): narrow the fan-out cap to the CPU encode burst only
The original cap held a process-global slot across the WHOLE vision
analysis (image load + encode + LLM call) with a default of min(CPUs, 4).
That serialized legitimate multi-image workflows — "compare these 6
screenshots", "read this 10-page scan", "analyze every frame" — behind a
4-wide gate, and on the native fast path it even throttled calls that make
no LLM request at all. Excess calls queued (blocking acquire, nothing
dropped), but the latency hit on real fan-out was the wrong tradeoff.

The incident was CPU exhaustion, not call count: concurrent base64/resize
bursts saturated every core and left none to service the shared event loop
serving /api/status. So cap ONLY that:

- A dedicated, bounded ThreadPoolExecutor (_vision_cpu_executor) runs the
  encode/resize/dimension-check off the caller's loop, sized to the host's
  usable core count with NO fixed ceiling — the cap tracks the actual
  exhausted resource (cores), not a magic number. Excess encodes queue on
  the executor; cores stay free for the loop.
- The LLM call is deliberately OUTSIDE the executor, so multi-image
  workflows keep full request concurrency.
- Override via auxiliary.vision.max_concurrency / HERMES_VISION_MAX_CONCURRENCY
  (honored verbatim, including above core count); sub-1 ignored.
- _vision_concurrency_slot() is now a no-op shim for back-compat.

Tests assert: resolver defaults to host cores with no ceiling; env/config
override (incl. above cores); sub-1 rejection; the executor is dedicated and
core-sized; encode runs on a vision-encode thread; and crucially that encode
bursts are bounded to the cap while the analyses themselves stay fully
concurrent (calls_peak > cap).
