Let Hermes Desktop update its native installation

-# Nous builds Hermes Desktop for macOS and Windows only -- their download page
-# offers a .dmg and an .exe and tells Linux users to install from a terminal --
-# so there is no vendor binary to repackage. Their electron-builder config does
-# carry a Linux target, though, and it works; this builds it.
-#
-# The app only runs against a Hermes runtime built from its own commit, so it
-# provisions one itself under ~/.hermes on first launch and the package stays
-# on the newest tag. Pairing it with the mise CLI instead was tried and does
-# not work: PyPI trails the tags, and the version gap fails the readiness probe
-# with a 401. Pinning back to the tag behind PyPI's release does not rescue it
-# either -- v2026.7.20's desktop hangs after "backend is ready" without ever
-# opening a window, against its own matching runtime.
-#
-# The app is only a shell: it runs `hermes serve` against a Hermes CLI it does
-# not ship, and clones its own copy with the upstream install script when it
-# finds none. /usr/bin/hermes-desktop heads that off. See hermes-desktop.sh.
