Every payload the job bundles is now asserted before packing: the console, the
bun runtime, the plugin runner, the FFmpeg DLLs and VB-CABLE. Each is optional
to pack-host-installer.ps1 — right for a local debug pack, and the reason
0.22.1 and 0.22.2 shipped with no web console: one unset variable omitted it
behind a single line of log and the build stayed green.
CI knows it bundles all five, so a missing input belongs here as a failure
rather than downstream as a quietly smaller installer. FFmpeg is the one that
would hurt most and was silent too: an amf-qsv host link-imports avcodec, so
an installer missing those DLLs ships a host that cannot start at all, and
FFMPEG_DIR is a fallback to a provisioned path that nothing verified.
The shape is borrowed from the packer's own VB-CABLE check, which already
throws on a supplied-but-empty dir "instead of silently shipping an installer
without the virtual mic - exactly the field regression this bundling fixes".
Same lesson, applied to the rest.
Both paths were exercised on the Windows runner: all five unset fails with
exit 1 naming each one, all five present passes with exit 0.
