SLB: Tune KS (DD) and Lambda (DD) builders

Ks⁰ (DD) cuts

• pi_pt_min 200→250 MeV
• pi_PID_K_max 5 -> 2
• bpvvdchi2_min 4→25
• vchi2pdof_max 30→10
• new ks_pt_min 600 MeV

Λ (DD) cuts

• p_pt_min 200→600 MeV
• lambda_pt_min 100→800 MeV
• bpvvdchi2_min 4→25
• vchi2pdof_max 25→10

In next iteration consider:

• Tightening PID cut for Lambda (DD) daughters.
• Tightening bpvvdchi2_min
