feat(A.5 T4): StreamingRegion ComputeFirstTickDiff

Browse source 
Adds the first-tick bootstrap diff: ToLoadNear for the (2*near+1)^2 inner
window, ToLoadFar for the outer annulus up to FarRadius. Uses Chebyshev
distance, matching existing Recenter convention.

Also renames the single-tier RecenterTo → RecenterToSingleTier to free
the canonical name for the upcoming two-tier overload (T5). Updates
StreamingRegionTests and StreamingController to call the renamed method.
