launcher: scan desktop files directly, keep state in XDG_STATE_HOME

bl/wldash

The desktop-entry cache lived in $XDG_CACHE_HOME/wldash/desktop.json.
On an NFS-shared home that is a remote read and write on every start
(unless the session happens to export a machine-local XDG_CACHE_HOME),
and it went stale whenever a package was installed until someone ran
--desktop-refresh. Scanning the applications directories takes a few
milliseconds over local /usr/share and already happened on a background
thread, so the cache bought nothing: drop it, along with simd-json and
the serde derives on Desktop. --desktop-refresh stays as a no-op so old
key bindings keep working.

Calculator history and the prompt saved on Escape are state, not cache:
they move to $XDG_STATE_HOME/wldash (~/.local/state), written only on
Enter/Escape, and the old cache location is still read as a fallback.

With the serde derives gone, two Desktop fields were unused; use them:
Type=Link entries now open their URL with xdg-open, and Terminal=true
entries run under $TERMINAL -e when it is set.
