Replace the Haar-cascade face detector with lightweight frame-differencing
motion detection so the daemon can poll every 20s (backing off to 120s under
heavy CPU/RAM load) without adding noticeable overhead.
Presence detection now shares caffeine's systemd-inhibit lock instead of
holding its own, so the caffeine status widget reflects either source. A new
ownership flag ensures the daemon only ever releases a lock it acquired
itself, so a manually-started caffeine session is never interrupted by the
user stepping away. Also re-enables the daemon in hyprlua's autostart (was
previously only wired up for niri).

- Add presence-detect.sh daemon: checks webcam every 2 min via OpenCV haar
cascade (presence_detect.py); holds systemd-inhibit --what=idle lock while a
face is detected so hypridle never fires during an active session
- Add enroll-biometrics.sh: Cyberqueer dialog TUI for camera configuration/test
and howdy face auth enrollment (add/list/remove/test models)
- Rewrite caffeine.sh (hyprlua + niri): replace kill/restart of idle daemon with
systemd-inhibit --what=idle:sleep + PID file; idle daemon stays running
- Fix hypridle.conf: correct ;; → ; in after_sleep_cmd, add
ignore_dbus_inhibit=false, bump lock timeout 120s→180s to account for the
2-min presence detection cycle
- Wire Super+Shift+B keybind for enrollment TUI in both hyprlua and niri
- Fix niri/scripts/python: was real dir with inner symlink causing cp -rL to
create a nested python/python/ hierarchy; replaced with direct symlink
- Add python-opencv and v4l-utils to hyprlua + niri installers
