bug: Portable Windows release zip is missing embedded executable icon in lapce.exe

Description

The portable Windows release (lapce-windows-portable.zip) contains a raw lapce.exe binary without an embedded icon resource.

When launched on Windows, the application icon on the taskbar falls back to the default system generic window icon (white box). Even if a shortcut with a custom icon is created, the running process on the taskbar continues to show the missing/generic icon because the executable itself lacks the embedded .ico resource.

Steps to Reproduce

1. Download lapce-windows-portable.zip from the latest release (e.g., v0.4.6).
2. Extract the zip file and launch lapce.exe.
3. Check the Lapce icon on the Windows Taskbar while the application is running.

Expected Behavior

lapce.exe should have the official Lapce icon embedded in its resources so that it displays properly in File Explorer and on the Windows Taskbar when running.

Actual Behavior

The taskbar shows a generic default Windows executable icon instead of the Lapce logo.

Environment

• OS: Windows
• Version: v0.4.6 (Portable)
