This pull request refactors how context menu items are contributed by extensions in the LiteGraph-based canvas. The legacy monkey-patching approach for adding context menu options is replaced by a new, explicit API (`getCanvasMenuItems` and `getNodeMenuItems`) for extensions. A compatibility layer is added to support legacy extensions and warn developers about deprecated usage. The changes improve maintainability, extension interoperability, and migration to the new context menu system. ### Context Menu System Refactor * Introduced a new API for extensions to contribute context menu items via `getCanvasMenuItems` and `getNodeMenuItems` methods, replacing legacy monkey-patching of `LGraphCanvas.prototype.getCanvasMenuOptions`. Major extension files (`groupNode.ts`, `groupOptions.ts`, `nodeTemplates.ts`) now use this new API.
