fix(engine): Linux GPU path uses deprecated EGL + NVENC probe fails on data-center GPUs (#1504)

Browse Source 
* fix(engine): use ANGLE-EGL for Linux GPU path, bump NVENC probe size

Chrome 131+ rejects --use-gl=egl in headless shell; the GPU process
exits and the renderer silently falls back to SwiftShader. Switch to
(gl=angle, angle=gl-egl) which is on the headless-shell allowlist,
and add --ignore-gpu-blocklist + --disable-software-rasterizer so
data-center GPUs (L4/T4/A10) are not blocked.

Also bump the NVENC probe frame from 16×16 to 320×240 — NVIDIA
data-center cards require ≥257 on each dimension and reject the
smaller size with "Frame Dimension less than the minimum supported
value", causing the encoder probe to silently fall back to libx264.

Closes #1493

* fix(engine): address review feedback — probe test, observability, comments

- Export getProbeArgs and add test pinning 320×240 probe dimensions
  across all 5 GPU encoder backends (nvenc/videotoolbox/vaapi/qsv/amf)
- Add driver/SKU rationale comment on the probe size constant with
  context about NVIDIA data-center card behavior vs documented minimums
- Add rationale comment on --ignore-gpu-blocklist (operator opted into
  hardware mode explicitly)
- Log resolved GL flags at browser launch for GPU fallback observability
