👋 A small follow-up to:

• fix(rspack): gate virtual folder behind process pid #538
• feat(rspack): use native virtual plugin #542

Basically a very simple gate to prevent inserting the process.pid() when the native virtual plugin is used, the rationale is:

• the native plugin writes virtual files in memory, so there should not be cross-process fs concurrency issues and the pid prefix is unnecessary
• the pid changes for every compilation, defeating long term caching strategies relying on the content hash
