* ci: skip ffmpeg-static CDN download on ubuntu; retry Windows FFmpeg install
ubuntu-24.04 runners ship /usr/bin/ffmpeg. Set FFMPEG_BIN so ffmpeg-static's
postinstall script skips its GitHub-release binary download, preventing bun
install failures when that CDN is unavailable.
For Windows: increase BtbN/FFmpeg-Builds download max-attempts 3→8 with
longer backoff (30×attempt s) and set FFMPEG_BIN after install so bun install
also skips ffmpeg-static's download in both render and test jobs.

* ci: fix FFMPEG_BIN approach — use writable copy via composite action
/usr/bin/ffmpeg is not writable by the runner user. When bun runs
ffmpeg-static's postinstall script in a context where process.exit(0) is
intercepted, the skip-if-exists check has no effect and the download proceeds
to the destination path. Pointing FFMPEG_BIN at a system path (/usr/bin/ffmpeg)
therefore causes EACCES even when the CDN returns 200.
Replace the top-level env var with a prepare-ffmpeg-bin composite action that
copies the system ffmpeg to $RUNNER_TEMP (writable). Call it before every
bun install step in the CI workflow. Whether the postinstall script skips or
overwrites, the write target is now writable and the job succeeds.

* ci: skip apt fallback in prepare-ffmpeg-bin; use stub when ffmpeg absent
ubuntu-24.04 GHA runners do not have ffmpeg pre-installed. The apt-get
fallback triggered the install of ffmpeg and its dependencies, but the
Azure apt mirror returned 404 for libcaca0, aborting the composite action.
ffmpeg-static's postinstall only needs a regular file to exist at FFMPEG_BIN
in order to reach the statSync check and call process.exit(0) — it does not
need a real executable. Write a minimal shell stub when 'which ffmpeg' returns
empty. Jobs that require an actual ffmpeg binary (cli-smoke-required) install
it via apt before calling this action, so 'which ffmpeg' returns the real path
and the copy branch runs instead.
