Pre-1.0 releases get the prerelease flag in Gitea — pre-1.0 means
public API may break between minors (SemVer permits this), so these
shouldn't display as stable releases.
Computed from $TAG via `case` so the flag auto-flips to false when
v1.0.0 lands; no further workflow change needed at that point.
case "$TAG" in
v0.*) prerelease=true ;;
*) prerelease=false ;;
esac
Passed to jq via --argjson (not --arg) so it stays a JSON boolean
rather than the string "true" / "false".
