Add missing C++ standard library includes

stanbot8 · stanbot8 · commit 938c7091226e · 2026-03-11T09:34:06.000-07:00
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.
