fix(dev-server): add .mf to ignoreWatching

[tseijp]

The change is minimal, adding .mf to ignoreWatching in vite-plugins/packages/dev-server/src/dev-server.ts.

// dev-server.ts
- ignoreWatching: [/\.wrangler/],
+ ignoreWatching: [/\.wrangler/, /\.mf/],

I've been developing with hono-x and cloudflare d1, but frequently encountered vite errors, causing the server to stop many time.

}

Even without file changes, the vite server kept reloading. Adding .mf to server.watch.ignore resolved the errors, suggesting .mf updates caused clashes.

  return {
    server: {
      watch: {
        ignored: [/\.wrangler/, /\.mf/],
      },
...

For reference, I'm using the following vite.config.ts. Developing with react and tailwind on hono-x has been very comfortable and enjoyable. Thank you!

import pages from '@hono/vite-cloudflare-pages'
import honox from 'honox/vite'
import { defineConfig } from 'vite'
import { getPlatformProxy } from 'wrangler'

export default defineConfig(async ({ mode }) => {
  if (mode === 'client') {
    return {
      build: {
        rollupOptions: {
          input: ['./app/client.ts', './app/style.css'],
          output: {
            entryFileNames: 'static/client.js',
            chunkFileNames: 'static/assets/[name]-[hash].js',
            assetFileNames: 'static/assets/[name].[ext]',
          },
        },
      },
    }
  } else {
    const { env, dispose } = await getPlatformProxy()

    return {
      server: {
        watch: {
          ignored: [/\.wrangler/, /\.mf/],
        },
      },
      ssr: {
        external: ['react', 'react-dom'],
      },
      plugins: [
        honox({
          devServer: {
            env,
            plugins: [
              {
                onServerClose: dispose,
              },
            ],
          },
        }),
        pages(),
      ],
    }
  }
})

I've been using cloudflare pages for a long time and am truly grateful. Typically using AWS or GCP for the backend, discovering hono led me to cloudflare's d1.
Given my limited experience with cloudflare d1, I would appreciate it if you could close my PR if it's off the mark.
Thank you!
