Wire up cache, file watcher, and Unix socket daemon

Adds a gen_server cache holding the rendered menu, an fs/inotify-based
watcher that debounces changes and invalidates it, a Unix domain
socket serving the cached binary, and the escript client Openbox
invokes (with an inline render fallback if the daemon isn't running).
Also documents local deployment (systemd user unit, Openbox menu.xml
wiring) in the README.
