README: ffmpeg-v4l2-request-fourier flipped to published

Build + publish landed (2:8.1.r123329.b57fbbe-3, Kwiboo's
v4l2-request-n8.1 tip + libudev-bypass companion patch). Deploy-host
verified on fresnel: installs cleanly, ffmpeg buildconf shows
--enable-v4l2-request, hwaccels list includes 'v4l2request', HEVC
decode via -hwaccel v4l2request produces correct-size output.

Quickstart per-host pacman -S lines now include
ffmpeg-v4l2-request-fourier. Status table flipped its row from
pending to published. Remaining pending: chromium-fourier
(clang 22 -> 23 blocker), qt6-base-fourier (Wayland GL_ALPHA fix).
