feat(hyprdrive): switch notifications from dunst to beacon

beacon (the Cosmonaut Shell notif daemon) already renders its holo
fade-in-from-noise intro (materialise out of static), but dunst held the
org.freedesktop.Notifications bus so beacon never started. Make beacon the
deployed and active notification daemon:

- updater.conf: manage `config beacon`; drop `config dunst` (now `ignore`d,
  superseded). Also carries the pre-existing `config ghostty` line that was
  already sitting uncommitted in this file.
- beacon: add a SIGUSR1 close-all handler (window.close_all) so the old
  `dunstctl close-all` keybind has an equivalent.
- binds.lua: Super+Ctrl+C now runs `pkill -USR1 -f '[b]eacon/main.py'`
  (bracket idiom avoids pkill self-matching its own wrapper).
- screenrec.sh: `dunstctl close` -> freedesktop CloseNotification via gdbus.
- timer-run: resolve the session bus via the beacon process, not dunst.

hyprlua keeps its own independent updater.conf + dunst and is untouched.
