lucemia/typed-ffmpeg v4.4 on GitHub

FFmpeg 9 support — typed-ffmpeg-v9, ffmpeg-data-v9 and @typed-ffmpeg/v9, generated from FFmpeg 9.0.1. Adds premultiply_dynamic, transpose_cuda and v360_vulkan; no filters were removed relative to v8
docker/ffmpeg-builder/Dockerfile.9.0, since jrottenberg/ffmpeg publishes no 9.x image

typed-ffmpeg now resolves to typed-ffmpeg-v9 instead of v8. typed-ffmpeg-compatible follows, so both entry points stay on the same FFmpeg major
Codegen consolidated into a single workflow. codegen-regenerate.yml and regen-bindings.yml are removed; the former had never succeeded in 100 runs
Generated bindings are now committed onto the pull request that changes the generator, so main never holds generator code without matching output

Published cache data was four months stale. ffmpeg-data-v* was written once in April and no workflow refreshed it; regenerated cache now reaches the published packages
ffmpeg-data-v8 contained a mix of 8.0 and 8.1 data, and ts-v8 was generated from 8.1 while the Python bindings came from 8.0
Codegen retries transient network failures; a single reset previously failed an entire run
Dependabot's uv updates, which had failed on every run since the manifests moved to a deprecated uv field
The large-filtergraph recursion fix from 4.0 finally reaches v5, v6 and v7 — only v8 had been regenerated at the time
mkdocstrings-python capped below 2.0, which removed an option the docs config uses
