fix(examples): use const char* const for global string constants

konegen · konegen · commit 3273dacb2376 · 2026-03-16T16:31:56.000+01:00
Pointers to string literals should be immutable themselves, not just
the pointed-to data. Applies to all embedded env.hpp/env.cpp.example
files and the http_test host constant.
