alpha version: quit command hangs/timeouts on Windows 10 PRO

[userquin]

Can be tested with the playground here (node v24.19.0):

• nr dev at root (one terminal)
• pnpm nuxt dev (in another terminal)
• open / and navigate to /ws, then click ping button
• on playground terminal press q: the process awaits the default timeout (15s) and then logs:

[nitro-runtime] close: 0.054ms

▲  The dev server did not shut down within 15s: 80 file watchers, 1 worker thread, 1 open connection, 2 timers. Exiting anyway.
◇  Canceled                                                                           

I added a hack to show the opened connections adding the following code before calling summariseActiveResources at setupSignalHandlers in dev.ts:

        const handles = (process as any)._getActiveHandles?.()
        const networkHandles = handles.filter(h => (
          h.constructor.name === 'Socket'
          || h.constructor.name === 'Server'
        ))
        console.dir(networkHandles, { depth: 2 })
        const summary = summariseActiveResources()

Moving this.#websocketConnections.add(socket) before the if statement to allow #closeWebSocketConnections to close also these connections, the 1 open connection dissapear.

I'm working on fixing file watchers...
