run: find versions of deps, useful for granular regression testing

[stewartboogert]

Need an easy way to determine what clhep, root and geant4 are installed

[Copilot]

Pull Request Overview

This PR adds a new Versions class to the Run.py module that detects and retrieves version information for ROOT, Geant4, and CLHEP by executing their respective config commands.

Key Changes:

• Introduced Versions class with methods to query version information from external tools (ROOT, Geant4, CLHEP)
• Added error handling for CLHEP version detection when the executable is not available

Comments suppressed due to low confidence (1)

src/pybdsim/Run.py:568

• Except block directly handles BaseException.

The exception handling catches CalledProcessError but doesn't check the return code before accessing stdout. If the command fails (non-zero exit code), stdout may still contain data but the exception will be caught. Add check=True parameter to subprocess.run() to properly raise CalledProcessError on non-zero exit codes.

The exception handling catches CalledProcessError but doesn't check the return code before accessing stdout. If the command fails (non-zero exit code), the code will attempt to parse stdout before the exception is caught. Add check=True parameter to subprocess.run() to properly raise CalledProcessError on non-zero exit codes.

Looks good. Only thing is that technically, your environment can be different from what BDSIM was compiled w.r.t. The other solution would be to add the functionality to BDSIM to report back what it was compiled with. If this technicality is ok for you then fine.

I think here creating a bdsim-config script or executable (very similar to geant4-config, clhep-config and root-config) would make a lot of sense in this case. Not a lot of work, but not worth it right now I feel.
