Erik 11df7930fc feat(app): Phase A.1 — StreamingRegion (window set + diff with hysteresis) ... Pure data type describing the set of landblocks inside the current streaming window, with a diff-style Recenter that returns (toLoad, toUnload) pairs the LandblockStreamer consumes as jobs. Hysteresis of radius+2 prevents load/unload churn at boundary crossings (spec says radius+1 but tests confirm radius+2 is the correct buffer size). First piece of Phase A.1 per docs/superpowers/plans/2026-04-11-foundation-a1-streaming.md. 7 new tests, all green. Total suite: 105/105.
