Rework the Eww caffeine widget into two independent inputs — manual inhibit
and presence detected — yielding four states across all three bars:
neither → sleep, purple
manual only → ☕ coffee, purple
presence only → eye, pink
manual + presence → ☕ coffee, pink
Colour tracks presence; the coffee cup shows only while manually inhibiting.
To make the two inputs independent, the daemon now writes a standalone
/tmp/presence-detected flag each tick (decoupled from lock ownership, so it's
true even during a manual session). presence-status.sh reports that flag
(presence input); new caffeine-manual-status.sh reports lock-held-and-not-
presence-owned (manual input).
Make detection less finnicky: space the detector's frame grabs (0.06s) so slow
movement registers and loopback reads never diff a stale duplicate frame, and
lower the thresholds (delta 25→18, area 2%→0.8%). Add a 90s grace window so
brief stillness never flickers presence off; any motion resets the clock.
Add a third poll tier — INTERVAL_FAST=2s when CPU-or-RAM usage is below 30%
(LOAD_LIGHT) — alongside the existing 20s normal and 120s busy tiers.

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
