There appears to be a bug in Rspack's CopyPlugin where it does not properly handle patterns that specify a single file. This functionality is supported in webpack's CopyWebpackPlugin, but it seems to be missing or not working as expected in Rspack.

No response

Reproduce Steps

1. Configure CopyPlugin in Rspack config
2. Attempt to copy a specific file using a pattern

{
  from: '/xx/xx.ts'
}

But /xx/xx.ts* is working

Expected Behavior:
The plugin should be able to copy a single, specific file when the pattern points to that file.

Actual Behavior:
The plugin fails to copy the file or throws an error (please specify the exact behavior you're seeing).
