…taUpTo ProcessScheduler.cpp (added in 827f185) calls peekCurrentRegion() and stepDeltaUpTo() on EventScheduler, but these methods were never declared in EventQueue.h or implemented in EventQueue.cpp, causing build failures. Add: - TimeWheel::peekCurrentRegion(): returns the next non-empty SchedulingRegion in the current delta without advancing the cursor (returns NumRegions if no events remain). - TimeWheel::processDeltaUpTo(limitRegion): processes all regions in the current delta up to and including limitRegion; advances the region cursor and cleans up empty queues. - EventScheduler::peekCurrentRegion(): thin wrapper around TimeWheel. - EventScheduler::stepDeltaUpTo(limitRegion): thin wrapper; updates stats.

Summary
ProcessScheduler.cpp(introduced in827f1855f) callspeekCurrentRegion()andstepDeltaUpTo()onEventScheduler, but these methods were never declared inEventQueue.hor implemented inEventQueue.cpp, causing build failures.This PR adds the missing declarations and implementations:
TimeWheel::peekCurrentRegion(): Returns the next non-emptySchedulingRegionin the current delta without advancing the cursor. ReturnsNumRegionsif no events remain in the current delta.TimeWheel::processDeltaUpTo(limitRegion): Processes all regions in the current delta up to and includinglimitRegion; advances the region cursor past the limit and cleans up empty queues. Returns the number of events processed.EventScheduler::peekCurrentRegion(): Thin wrapper delegating toTimeWheel.EventScheduler::stepDeltaUpTo(limitRegion): Thin wrapper; updates event and delta-cycle stats.Test plan
