Mark macOS bin icons as template images(fixes dark theme bin icon in right-click menu)

[jamesx0416]

What Changed

• Mark the resized macOS native trash icon used for destructive Electron context menu items as a template image.
• Add a regression test covering destructive macOS context menu icon creation.

Why

The native trash icon was rendering as a fixed black bitmap in dark mode after being resized. Calling setTemplateImage(true) lets macOS tint the menu icon correctly for the current menu
appearance.

UI Changes

This fixes the dark-mode color of the trash icon shown next to destructive native context menu actions, such as removing a project from the sidebar.

Note

Low Risk
Low risk: macOS-only UI tinting change for a native menu icon plus a targeted regression test; no changes to menu selection logic or data handling.

Overview
Fixes macOS destructive context menu icon rendering by calling setTemplateImage(true) on the resized native trash icon so it can be tinted correctly (e.g., in dark mode).

Adds a regression test that forces process.platform to darwin and asserts the icon is created, resized, marked as a template image, and passed through to the built menu template.

Note

Mark destructive macOS context menu icons as template images

Calls setTemplateImage(true) on the resized trash icon in getDestructiveMenuIcon before caching it, so macOS renders it correctly in both light and dark menu appearances. A corresponding test in ElectronMenu.test.ts verifies the full icon creation, resize, and template-marking sequence on darwin.
