ffmpeg-next 8.1.0 could not accept FFmpeg 9 at all: ffmpeg-sys-next's version probe
covered avcodec majors 56..62 (the range is exclusive of its end), so libavcodec 63 fell
outside what it knew how to bind. 9.0.0 widens that to 56..63, which is what actually
unblocks Arch. Bump both pins — the unconditional Linux dep and the optional Windows
amf-qsv one — and the lock with them.

No API drift to fix. The crate major is a CEILING, not a target: one source tree still
spans FFmpeg 7.x/libavcodec 61, 8.x/62 and 9.x/63 via per-version cfgs, and every wrapper
symbol the NVENC-libav, VAAPI and amf-qsv backends name survives 8.1.0 -> 9.0.0
unchanged. The three hand-written #[repr(C)] hwcontext mirrors are the parts no compiler
checks, so they were re-read against the real headers rather than trusted:
AVCUDADeviceContext and AVD3D11VAFramesContext are byte-identical across 7.1/8/9, and
AVD3D11VADeviceContext gained two trailing UINTs in 8 that 7.1 lacks — which is why that
mirror deliberately stops at the common prefix, and why its assertions now say what they
do and do not buy you. They pin our layout, not libav's; a green build is not evidence.

The CI image is the step that makes this reach users. arch.yml deliberately runs no -Syu
("the image's snapshot IS the build environment"), so the builder stayed frozen on ffmpeg
8 no matter what Arch shipped, and a canary built from that snapshot could not satisfy the
soname dep the PKGBUILD now derives. Re-keying ci/ rebuilds it against ffmpeg 9.

Ubuntu and Windows deliberately stay put: the noble .deb bundles its own FFmpeg 8 behind
an rpath and strips the libav sonames from its Depends, and Windows bundles BtbN DLLs into
the signed installer — neither is exposed to the break, BtbN publishes no FFmpeg 9 build,
and moving either would re-qualify an encode stack to buy nothing.

Verified end to end on 192.168.1.21 (CachyOS, system ffmpeg 2:9.0-5, RTX 5070 Ti): host
builds clean and links libavcodec.so.63/libavutil.so.61/libavfilter.so.12/libswscale.so.10
with no unresolved sonames; the ffmpeg-8 compat shim is gone and the service runs with
NRestarts=0 and answers 401 on :47990; pf-encode's 67 tests pass; and a live synthetic
encode drives real NVENC hardware through FFmpeg 9's libavcodec to a decodable 1080p HEVC
stream (180/180 frames, FEC loopback 0 mismatches) with libavcodec.so.63 and
libnvidia-encode both mapped into the encoding process.
