Add Linux Ctrl+= alias for Zoom In shortcut

[Mohatje]

Closes #852

What Changed

• added a Linux-only menu item to register Ctrl+= as a zoom-in alias

Why

• Ctrl + = is expected as the keybind to zoom-in without having to press Ctrl and shift at the same time.

Checklist

• [ x ] This PR is small and focused
• [ x ] I explained what changed and why
• [ N/A ] I included before/after screenshots for any UI changes
• [ N/A ] I included a video for animation/interaction changes

Note

Add Ctrl+= as a Linux alias for the Zoom In shortcut

On Linux, Ctrl++ and Ctrl+= are distinct key combinations, so the standard zoom-in accelerator misses the = key. A hidden menu item with role: zoomIn and accelerator: Ctrl+= is conditionally added in main.ts when process.platform === 'linux'.

🟡 Medium src/main.ts:590

The Zoom In Alias menu item is added to the top-level menu template with visible: false, but Electron ignores this property on Linux top-level items. As a result, users see a literal "Zoom In Alias" entry in the menu bar (File Edit View Zoom In Alias Window Help). Place this item inside the View submenu instead, where visible: false is respected.

-    { role: "viewMenu" },
-    ...(process.platform === "linux"
-      ? [
-          {
-            label: "Zoom In Alias",
-            accelerator: "Ctrl+=",
-            role: "zoomIn" as const,
-            visible: false,
-          },
-        ]
