The package was named for its first job; it now also decides what a file is for the
Files tab (image, video, audio) and reads its streams, which the viewer will need. Inspect
is the richer probe — codec, profile, pixel format, size, frame rate, HDR transfer, the
audio beside it, container and duration — run as root through sudo when asked.

bbolt instead of a tree of hash-named JPEGs: pure Go, so the binary stays static; one
file per machine; an entry carries where the preview came from (engine, codec, size,
when) beside the picture, and a count rides along so the tab can say what it holds
without walking anything. A miss never creates the file, so a machine nobody browses
with previews on never has one; a cache that cannot be opened is logged and previews
are still made and served, just not kept.

A previews button on the Files tab turns the icon column into a 256 px thumbnail for
every image and video row, loaded as rows scroll near. internal/thumbs probes what the
machine can do rather than assuming it: ffmpeg and ffprobe, every /dev/dri/renderD*
opened and exercised, vainfo's decode profiles per node where it exists. A video goes to
the first GPU that lists its codec, with ffmpeg's own software fallback behind it and a
CPU retry behind that; images decode on the CPU, JPEGs at a reduced DCT size. Previews
are kept under <data dir>/thumbs/ keyed by path, size and mtime, with undecodable files
remembered too. Root mode makes them through the same root helper the file reads use.
Where ffmpeg is missing the tab offers to install it; where a render node exists but is
closed to the daemon's user, it offers a drop-in adding the group and a restart.
