This PR:

  • Simple lambda/photon analysis option:
    Adds the possibility to run a simple - yet complete - analysis over photons, lambdas, and antilambdas using the sigma0builder task. This mode is intended primarily for QA and cross-checks.

  • Refined selection cuts:
    Updates rapidity, pseudorapidity, and z-position selections across all tasks. It is now possible to define selection ranges (min/max values), instead of only absolute thresholds. This enables studies of how the analysis behaves when selecting V0s on different TPC sides.

  • Additional QA histograms:
    Introduces a set of QA histograms to support MC-association sanity checks.

  • New index tables:

    • SIGMAINDEX: links SIGMA0CORES -> V0CORES
    • SIGMAMCLABEL: links SIGMA0MCCORES -> MCPARTICLES
  • Configurable histogram declarations:
    Adds configurables to disable unused histograms, reducing memory usage.

More features and minor adjustments will be introduced in a subsequent PR.
