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!#
