Subject: [PATCH] Lane F R4: wire citizens.setExposure (F1) + permittedMax
 storeys-checker fix (F2)

F1: pass renderer.toneMappingExposure into CitizenSim each street frame so mid-tier
impostors track the animated day/night exposure (per LANE_D_NOTES). Verified: boots
clean, 0 console errors, exposure animates night 1.18 <-> midday 0.98.

F2: scope the consistency storeys check to permittedMax = max>=2 ? min(max+1,3) : max
(Lane A's corner-anchor rule, LANE_A_NOTES R3). Consistency now 0 warnings across 6
seeds; a single-storey type at >1 still trips. qa.sh --strict GREEN 4/4.
