`update` fetches the latest release tag from the GitHub API (or takes
--version), downloads the cross-platform python zipapp, and installs it
into archivr's state dir. The install is atomic — staged as yt-dlp.new,
chmod +x'd, then renamed over the target — so a concurrently running
capture never sees a half-written binary. A sibling .version file makes a
repeat update a no-op instead of a 3MB re-download.
The download is checked for the python3 shebang before install, which
catches the usual failure mode of getting an HTML error page back. python3
itself is only warned about, not required: the server may run under a nix
wrapper with its own PATH.
`status` prints all three candidates (env / state-dir / PATH fallback) with
their versions and stars whichever the resolver picks, so it is obvious
which yt-dlp a capture will actually use.
reqwest is pulled from the existing workspace dependency; the GitHub JSON is
parsed with serde_json so the "json" feature is not needed.
