extension_builder does not use project environment PATH?
Summary
Building a dev extension is not possible if rustc is not in the system PATH
Description
I'm on a system where rustc is not directly in the PATH, but requires some environment setup. In a shell that's correctly setup (rustc --version works) I start zed (using zed .) and choose the "Install dev extension" action, but the build fails because rustc is not found.
In my case I'm using a nix flake to manage the rust version, but any setup where the PATH first needs to be set for rustc to become available would be the same I suppose.
Steps to reproduce:
- Have a Rust install in a path outside the system PATH
- Start a shell where rustc is available (PATH set to correct value)
- Start zed from that shell
- Use the "Install dev extension" action
Expected Behavior: Build fails because rustc is not found
Actual Behavior: zed uses the parent shell environment and builds the extension using the correct rustc version
