🚀 Feature Request: inform VSCode, etc. of JSONC parsing for wrangler.json

[Cherry]

Describe the solution

When initialising a new worker with C3 today, you're given a wrangler.json that looks something like this:

/**
 * For more details on how to configure Wrangler, refer to:
 * https://developers.cloudflare.com/workers/wrangler/configuration/
 */
{
	"$schema": "node_modules/wrangler/config-schema.json",
	"name": "solitary-rice-5b9c",
	"main": "src/index.ts",
	"compatibility_date": "2025-01-24",
	"observability": {
		"enabled": true
	},
	"compatibility_flags": [
		"nodejs_compat"
	]
	/**
   * Smart Placement
   * Docs: https://developers.cloudflare.com/workers/configuration/smart-placement/#smart-placement
   */
	// "placement": { "mode": "smart" },
	/**
   * Bindings
   * Bindings allow your Worker to interact with resources on the Cloudflare Developer Platform, including
   * databases, object storage, AI inference, real-time communication and more.
   * https://developers.cloudflare.com/workers/runtime-apis/bindings/
   */
	/**
   * Environment Variables
   * https://developers.cloudflare.com/workers/wrangler/configuration/#environment-variables
   */
	// "vars": { "MY_VARIABLE": "production_value" },
	/**
   * Note: Use secrets to store sensitive data.
   * https://developers.cloudflare.com/workers/configuration/secrets/
   */
	/**
   * Static Assets
   * https://developers.cloudflare.com/workers/static-assets/binding/
   */
	// "assets": { "directory": "./public/", "binding": "ASSETS" },
	/**
   * Service Bindings (communicate between multiple Workers)
   * https://developers.cloudflare.com/workers/wrangler/configuration/#service-bindings
   */
	// "services": [{ "binding": "MY_SERVICE", "service": "my-service" }]
}

VSCode (and likely other editors) get very upset at this by default, as .json doesn't support comments by default - only with JSONC flavour parsing.

If I add a .vscode/settings.json with this:

{
	"files.associations": {
		"wrangler.json": "jsonc"
	}
}

VSCode stops screaming and is happy with parsing this is as jsonc. I wonder if it could make sense to ship something like this by default? Or a .jsonc by default for better cross-editor compatibility?

I'd +1 the .jsonc by default, I'm not sure other editors like Zod look at the .vscode/settings.json and those other editors are becoming more and more popular.
