Fixes incorrect call of super in the Janin analysis class.

This error was detected when doing a trial run of CodeQL, see https://github.com/MDAnalysis/mdanalysis/security/quality and in particular https://github.com/MDAnalysis/mdanalysis/security/quality/rules/py%2Fsuper-not-enclosing-class

The "generate fix" disregards our standard PR template and adds the text below. For compliance, I manually inserted the PR text from

LLM / AI generated code disclosure

LLMs or other AI-powered tools (beyond simple IDE use cases) were used in this contribution: yes

The fix was auto-generated, i.e., full AI use. However, that was simply faster than me making the equivalent edit.

Autofix-generated text

The fix is to make the super() call reference the enclosing class (Janin) so object initialization follows the correct MRO and calls the intended base-class constructor.

Best minimal fix (no behavior change beyond correcting initialization): in package/MDAnalysis/analysis/dihedrals.py, replace:

  • super(Ramachandran, self).__init__(...)

with:

  • super(Janin, self).__init__(...)

No new imports, methods, or dependencies are required.
