Fixed: mv command in Bun Shell

In Bun v1.0.31, the mv command in Bun Shell regressed and in several scenarios would not move files and instead throw an error.

This has been fixed thanks to @zackradisic, and we've added tests to prevent this from happening again.

Fixed: node:crypto id values for sign function

Our node:crypto implementation was missing the id values for the sign functions. This has been fixed.

The node-forge and acme-client npm packages now work in Bun, thanks to @zenshixd.

Windows support is close

We are close to shipping Windows support with Bun v1.1. Once Bun for Windows passes 95% of Bun's test suite, we will announce the release date.

Thank you to 4 contributors!
