Detailed Description

Minimal scheduler for coupled systems: advance_subcycled reads each block's time policy (traits block_substeps_v / block_stride_v / block_time_treatment_v) and calls a user callable on the substeps.

Layer: include/pops/numerics/time. Role: physics-agnostic skeleton. Enables per-block cadences (e.g. electrons 10 implicit substeps, ions 1 explicit step) without hard-coding any logic in a single-model Coupler. Prescribed blocks are skipped.

Invariants:

substeps (split: n steps of dt_eff/n) and stride (cadence: advance 1 macro-step out of stride, then by an EFFECTIVE step stride*dt) are ORTHOGONAL; over M macro-steps the total stays M*dt;
a strided block advances only at macro-steps that are multiples of stride (otherwise return);
the overload without macro_step forces macro_step=0 (all blocks advance, stride ignored) -> bit-identical to the old advance_subcycled; stride=1 = historical behavior.
