Logging in via a bare Hyprland session never activates
graphical-session.target, so the systemd xdg-desktop-portal units can't
start. The old script worked around this by killing and relaunching the
portals manually, but that delayed the portal past waybar/chromium
startup, so they intermittently came up in light mode.
Switch to the "Hyprland (uwsm-managed)" session: uwsm activates
graphical-session.target and systemd starts the portals in the right
order. The startup script now detects that target and bows out, falling
back to the manual launch only on a bare session (e.g. another machine
without uwsm). Document uwsm in the README.

Also to start it, for some reason it needs to be killed and
there needs to be a sleep, etc. to avoid some race conditions.
Therefor I added this weird shell script to start it.
