This PR introduces a new macro, DETOUR_CUSTOM_STATIC2, to unify detour declarations across different platforms and Source Engine versions, improving code readability. - Linux i386 (TF2) → uses __attribute__((regparm(2))) - Windows (CSGO) → uses __fastcall - All other platforms → falls back to standard DETOUR_DECL_STATIC2 By consolidating detour declarations into a single macro, code is easier to read, maintain, and less error-prone across different platforms and ABIs.
