Mike-Solar 05e42668cb build(ffmpeg): static GPL FFmpeg 8.0 via project script + FFMPEG_DIR
- tooling/ffmpeg/build-ffmpeg.sh builds release/8.0 static+PIC into
  .cache/ffmpeg: GPL/version3, every free-license external codec lib
  probed via pkg-config (enabled when present), per-OS hardware
  acceleration (VideoToolbox/AudioToolbox, VAAPI/VDPAU/libdrm,
  D3D11VA/DXVA2/MediaFoundation, nvenc when ffnvcodec exists)
- tooling/install-deps.sh installs those libraries on Homebrew / MSYS2
  UCRT64 / Debian-Ubuntu / Fedora / Arch; nothing in the build sudo's
- ffmpeg-next's own build feature is unusable (every crate-version to
  FFmpeg-release pairing is broken upstream: 9.0.0->FF9 AVCodec fields,
  8.1.0->FF8.1 new enum variants, 8.0.0->FF8 FF_PROFILE rename), so
  ffmpeg-next 9 + FFmpeg 8.x headers via FFMPEG_DIR it is
- new links-crate oakffmpeg-link emits the static FFmpeg's transitive
  link flags from its .pc files (cargo only propagates them from links
  crates, and rustc prunes the flags unless the rlib is referenced —
  hence the force_link statics)
- docs/build.md updated for the Rust workspace flow

//! Empty crate whose build script emits the transitive link flags of a
//! static FFmpeg (see build.rs). Depend on it from every crate that uses
//! `ffmpeg-next` so the final binary/test links.
/// Referenced by dependents (`#[used] static … = force_link`) so this
/// rlib is never pruned as unused — the build script's native link flags
/// only reach the final link while the rlib is linked.
