/*
* NContextMenu - Popup-based context menu for use inside panels and dialogs
*
* Use this component when you need a context menu inside:
* - Settings panels
* - Dialogs
* - Repeater delegates
* - Any nested component context
*
* For bar widgets and top-level window contexts, use NPopupContextMenu instead,
* which provides better screen boundary handling and compositor integration.
*
* Usage:
*   NContextMenu {
*     id: contextMenu
*     parent: Overlay.overlay
*     model: [
*       { "label": "Action 1", "action": "action1", "icon": "icon-name" },
*       { "label": "Action 2", "action": "action2" }
*     ]
*     onTriggered: action => { Logger.i("MyModule", "Selected:", action) }
*   }
*
*   MouseArea {
*     onClicked: contextMenu.openAtItem(parent, mouse.x, mouse.y)
*   }
