Add missing C++ standard library includes

stanbot8 · stanbot8 · commit 3e5865b33c58 · 2026-03-12T13:54:15.000Z
log_range_param.h and range_param.h rely on &lt;cmath&gt; being transitively
included through other headers. Adding explicit includes ensures correct
builds regardless of which headers are pulled in by dependencies.
