Websockets feature does not work with vite running in through bun

[TheComputerM]

Environment

Nitro: 3.0.260311-beta
Bun: v1.3.11
Node: v25.8.1

Reproduction

Simple vite + nitro project

import { nitro } from "nitro/vite";

// vite plugins
		nitro({ preset: "bun", features: { websocket: true } }),

Then run

bunx --bun vite dev --port 3000

Describe the bug

https://github.com/nitrojs/nitro/blob/main/src/runtime/internal/vite/dev-entry.mjs will always load the node version of crossws, even if vite is running through bun mode.
