Tear down the mise Hermes CLI on Remove Hermes

Remove Hermes dropped the desktop package and its ~/.hermes runtime but
never touched the mise CLI, on the assumption the install-time handoff
had already removed it. A CLI the app never superseded -- an interrupted
install, or the terminal CLI from before the app existed -- was left
stranded on PATH after uninstall.

Add a --remove mode to omarchy-install-hermes-cli that performs the same
teardown the desktop takeover already does (mise rm -g + mise uninstall,
and the marked stub), and call it from omarchy-remove-ai-hermes. The tool
spec and ownership marker stay defined in one place, so the takeover and
teardown paths cannot drift. Scoped to what Omarchy owns: a Hermes the
user installed themselves is left alone.
