Functions
auto	zxfoundation::sched::pelt::accumulate_sum (u64 delta_ns, sched_avg &sa, u32 load, u32 runnable, u32 running) noexcept -> u32
	Accumulate a signed-delta running contribution into a PELT averaging record, advancing by zero or more full periods.
auto	zxfoundation::sched::pelt::decay_load (u64 value, u64 periods) noexcept -> u64
	Decay a load value by n full periods.
auto	zxfoundation::sched::pelt::update_entity_load_avg (sched_avg &sa, u64 now_ns, u32 weight, u32 runnable, u32 running) noexcept -> void
	Drive a full per-entity PELT update cycle.
auto	zxfoundation::sched::pelt::update_load_avg (sched_avg &sa, u32 weight) noexcept -> void
	Fold the decayed sums into the public averages.
auto	zxfoundation::sched::pelt::update_rq_load_avg (sched_avg_rq &rq, u64 now_ns, u32 runnable) noexcept -> void
	Drive a full per-RQ PELT update cycle for sched_avg_rq.
