Detect the latest stable release tag with the system git binary instead of an HTTP client, avoiding a C-compiler/TLS build dependency on the static musl target. Pure helpers (parse_ls_remote_tags, latest_stable_tag, compare_versions, notify_line, cache_is_stale) are unit-tested; fetch and the two entry points are thin glue.

This was chosen over an HTTP client + the Releases API becauseureq+rustls pulls inring, which breaks the static-musl build (needs a musl C compiler).ls-remotetags, filter to stablevX.Y.Ztags, pick the highest by numeric semver.~/.cache/git-supervisor/version-check.json), runs on a blocking thread, and swallows all errors so it never interruptswatch.Test Plan
