* refactor: streamline OxiCloud installation process by using prebuilt binaries
* oxicloud: take the prebuilt binary in the update too
Upstream now attaches musl tarballs to every release (AtalayaLabs/
OxiCloud#533), so the update no longer has to install a Rust toolchain
and Node and compile for up to 35 minutes. That compile is also what
broke #16216: a release whose source did not build left users with a
failed install and no way forward.
The tarball carries one top-level directory, which the deploy helper
strips, so the binary lands at /opt/oxicloud/oxicloud. The frontend is
baked into it, so the SPA build and OXICLOUD_STATIC_PATH both go; the
variable is commented out rather than removed, since a stale ./static
path would otherwise point at a directory that no longer exists.
migrate-nfc-filenames is gone as a separate binary - it is now a
subcommand, oxicloud migrate nfc-filenames - so the update removes the
old one. ffmpeg replaces build-essential: the server forks it for video
thumbnails and it is the one runtime dependency the musl build still
needs from the system.
Defaults drop to 2 CPU and 2048 MB, which were sized for the compile.
* oxicloud: install ffmpeg on update as well
The install gained it, the update did not, so a container created before
this change would never get it. The musl binary forks ffmpeg for video
thumbnails; without it that one feature stays silently unavailable.
