fix: handle monitor hotplug for greeter windows (v0.8.2)
Update PKGBUILD version / update-pkgver (push) Successful in 2s
Details

Browse Source 
Greeter windows were only created at startup. Hotplugged monitors (e.g.
HDMI reconnect) would show no UI. Connect to the monitor ListModel's
items-changed signal to create greeter windows for newly added monitors.

Aligned with moonlock's hotplug fix using the same pattern adapted for
gtk4-layer-shell (ListModel) instead of session-lock (connect_monitor).

# Decisions
## 2026-04-09 – Monitor hotplug via ListModel items-changed
- **Who**: ClaudeCode, Dom
- **Why**: Greeter windows were only created at startup. If a monitor was hotplugged (e.g. HDMI reconnect), it would show no greeter UI. Aligned with moonlock's hotplug fix (same day).
- **Tradeoffs**: Hotplugged monitors get greeter windows without keyboard input (keyboard stays on the primary monitor). Acceptable — user can still interact on the primary screen.
- **How**: Connect to `display.monitors().connect_items_changed()` and create new greeter windows for added monitors. Shared state (config, texture, blur_cache) moved to Rc for the closure.
## 2026-04-08 – Show greeter UI on all monitors instead of just one
- **Who**: ClaudeCode, Dom
