[Enhancement] Generate language-specific overrides in .vscode/settings.json

[vpckso]

Description

The Problem

When generating configurations for VS Code, the current template only outputs a global editor.defaultFormatter.

Because of VS Code's Settings Precedence, any language-specific configuration in a user's global settings.json will take priority over a workspace-level global setting. This means if a user has Prettier set specifically for TypeScript in their global settings, the generated workspace setting for oxc-vscode is ignored.

Precedence Conflict

1. User Settings (Global - High Priority):

   "[typescript]": { "editor.defaultFormatter": "esbenp.prettier-vscode" }

2. Generated Workspace Settings (Low Priority):

   "editor.defaultFormatter": "oxc.oxc-vscode"

Result: VS Code uses Prettier, ignoring the project's intent to use OXC.

Suggested solution

When the VS Code configuration is generated, the tool should include language-specific blocks based on the project template (e.g., [typescript], [typescriptreact], [javascript]). This ensures the workspace setting correctly overrides any existing user-level language settings.

Target Output for .vscode/settings.json for typescript react project:

{
  "editor.defaultFormatter": "oxc.oxc-vscode",
  "[typescript]": {
    "editor.defaultFormatter": "oxc.oxc-vscode"
  },
  "[typescriptreact]": {
    "editor.defaultFormatter": "oxc.oxc-vscode"
  }
}
