Debug Auto Attach Support

[Malix-Labs]

Workaround

I did succeed to make a custom launch.json to launch a chrome dev window and attach the vscode debugger to it

launch.json

{
	"version": "0.2.0",
	"configurations": [
		{
			"name": "Launch Chrome",
			"request": "launch",
			"type": "chrome",
			"url": "http://localhost:5173",
			"webRoot": "${workspaceFolder}/src",
			"preLaunchTask": "deno: dev (parallel)"
		}
	]
}

But at this point, there stil is a problem in that preLaunchTask does wait for the task to finish, but the usual deno: dev / deno run dev task which binds to vite dev is long-lived (meaning it should stay alive during the debugging session).
See my feature request to make it allowed to be a background task instead : microsoft/vscode#232200

A workaround for this second issue is to make a custom user task of the deno provided deno: dev task :

tasks.json

{
	"version": "2.0.0",
	"tasks": [
		{
			"type": "deno",
			"command": "task",
			"args": [
				"dev"
			],
			"problemMatcher": [
				"$deno"
			],
			"label": "deno: dev (parallel)",
			"detail": "$ vite dev",
			"isBackground": true
		}
	]
}	

Now, it should work reliably, but it is far from working out of the box nor auto attaching automatically
