Pull request overview
This PR extends the PWGLF phi–strangeness correlation workflow to support Phi–Xi correlations by adding a reduced Xi candidate table/producer and integrating Xi as an associated species in the correlation task, alongside a refactor that generalizes “associated particle” handling.
Changes:
- Add reduced Xi candidate AOD tables and a new XiReducedCandProducer to populate them.
- Extend the phiStrangeCorrelation analysis task with Xi configurables, histograms, and SE/ME processing paths.
- Refactor associated-particle processing using templated helpers to share logic across K0S/Xi/Pion.
