Detailed Description

Built-in state IO plugin — wraps HotStartManager for read/write.

Provides the default IStateIOPlugin implementation. Reads and writes the OpenSWMM OPENSWMM_HS_V1 / V2 binary hot-start format (and recognises legacy SWMM5-HOTSTART* files for read).

Solver-internal state (infiltration, groundwater) flows through SimulationContext::state_accessors, wired by SWMMEngine at open() time. The plugin itself holds no references to engine subsystems and is fully self-contained.
