This PR adds a new PWGCF workflow, flow-fluc-gfw-pp, for Event Shape Engineering studies in pp collisions.
The task uses the GFW framework to calculate multi-particle azimuthal correlations. Events are classified according to the reduced second-order flow vector q_2. The resulting correlation profiles are stored in FlowContainer objects for later cumulant and v_2 extraction. The physics motivation is to study whether high-q_2 pp events show enhanced v_2-related observables, and to investigate the role of fluctuations and non-flow effects in small systems.
