Why: Refactor mouse capture logic to use robust input‑region handling, add support for multi‑click events, and align layer usage with the passed layer parameter; update dropdown to use an Escape keybinding instead of a button‑press hide.
New Features:
- Support button‑press, double‑click, and triple‑click events.
- Introduce `_get_child_window_bounds` helper and window‑local coordinate detection for accurate click placement.
- Add cursor‑feedback styling updates on the trigger widget.
Enhancements:
- Make overlay layer configurable via the passed `layer` argument.
- Replace direct `button-press-event` connection with an Escape keybinding in the dropdown.
- Update imports to use `Gdk` and new utilities (`HyprlandWithMonitors`, `modus_service`).
Bug Fixes:
- Resolve race condition that could hide child windows on external clicks.
- Ensure immediate hide when clicking outside the child window to avoid timing issues.
- Correct click‑inside detection logic and properly consume events.
