Angular CLI frontend cannot run with wails3 dev because --strictPort is passed

[neupaneanish]

Description

I am trying to use Angular CLI as the frontend framework with Wails v3.

The frontend builds successfully, but wails3 dev cannot start the Angular development server because Wails passes the Vite-specific --strictPort argument.

To Reproduce

1. Create a Wails v3 project.
2. Replace the frontend with an Angular CLI application.
3. Add the following script:

  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "dev": "ng serve",
    "build:dev": "ng build --configuration development ",
    "build:prod": "ng build --configuration production",
    "watch": "ng build --watch --configuration development",
    "test": "ng test"
  }

Expected behaviour

Wails should support Angular CLI as a frontend dev server without passing Vite-specific arguments.

When running wails3 dev, Angular should receive compatible arguments, for example:

ng serve --port 4200

This keeps it focused on the expected outcome rather than prescribing only one implementation.
