The changes in this commit focus on improving the selection of He-V0 candidates by introducing a 2-body vertex finding step. The key changes are: 1. Added a 2-body vertex fitter (DCAFitterN<2>) to process the positive and negative tracks and obtain the PCA (point of closest approach) candidate. 2. Calculated the cosine of the pointing angle and applied a cut on this value to further select the He-V0 candidates. 3. Refactored the existing He-V0 selection logic to use the new 2-body vertex information.
