chore(engines): refresh ffmpeg provider builds

Update Windows and Linux FFmpeg source locks to BtbN 8.1.2-22-g94138f6973 from autobuild-2026-07-06-14-19.

Replace the bundled macOS Apple Silicon FFmpeg binary with Martin Riedl snapshot N-125450-gfad2e0bc50 and record its verified checksum.

Teach the update checker to compare FFmpeg provider builds separately from upstream stable releases so future refreshes are not missed.

Keep yt-dlp pinned at the current official stable 2026.07.04 and update Vitest to 4.1.10 so the release update gate stays clean.
