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.
