After the primary cell's BSP returns OK, query every other cell the foot-sphere overlaps via CellTransit.FindCellSet + Transition.CheckOtherCells. Closes the Holtburg inn vestibule wall walk-through: the vestibule (cell 0xA9B40164) has only 4 BSP polys; walls live in the adjacent interior cell (0xA9B40157). Without A4 the adjacent cell's BSP was never queried. End-to-end test reduces the real Holtburg bug to a minimal synthetic two-cell fixture: empty vestibule BSP + interior cell with the existing BSPStepUpFixtures.TallWall (the same fixture B2 uses to prove a grounded mover can't scale a 5m wall). Pre-A4: returns OK (walks through). Post-A4: returns Slid (the wall halts the transition). FindEnvCollisions visibility tightened from private → internal so the integration test can call it directly without going through FindTransitionalPosition's sub-step iteration.
