#5278 [BUG] set_cover Python: integer focus overloads are unreachable, and a bool in_focus mask crashes GreedySolutionGenerator on a fresh invariant

#5341 SetCoverLagrangian: stale ThreePhase() declaration, and ComputeLowerBound() segfaults if UseNumThreads() was not called

#5059 Add ability to opt-out from NoOverlap -> Alldiff conversion in presolve

#5310 Allow Dual ray extraction for infeasible LPs when solved using primal simplex in GLOP (via Mathopt)

#5292 CP-SAT: Segmentation fault using num_workers > 4 on attached model

#5301 CP-SAT model hanging in macOS if running with more than one search worker

#5297 CP-SAT 9.15.6755: memory-safety regression building large models — `std::bad_alloc` via `repr(IntVar)` and heap corruption (0xC0000374) via `IntVar.Proto()` (works on 9.14)

#5302 model_builder (Python): add_enforced_linear_constraint corrupts an unrelated constraint or segfaults (writes via non-enforced setters)

#5274 CP-SAT returns INFEASIBLE with presolve enabled but OPTIMAL with presolve disabled

#5295 # CP-SAT returns a false INFEASIBLE at the root (0 conflicts, 0 branches) with `num_search_workers >= 10` and `cp_model_presolve = false`

#5296 (Question) There's a typo in repository description?
