[codex] Use non-reserved header guards

+## Header Guards
+
+For every project-owned C/C++ header, use `#pragma once` together with a
+non-reserved include guard. Guard names must be derived from the project prefix
+and header path, and must clearly indicate that the macro is a header guard:
+
+```cpp
+LOGIT_CPP_HEADER_<PATH>_<FILE>_<EXT>_INCLUDED
+```
+
+Do not use identifiers reserved for the compiler, standard library, platform SDK,
+or other implementation internals. In particular, do not use include guard names
+that start with an underscore, start with an underscore followed by an uppercase
+letter, or contain a double underscore anywhere.
+
+Implementation fragments such as `.ipp`, `.inl`, or `.tpp` files may remain
+unguarded if they are only included from already guarded headers and are not
+intended for direct inclusion. If they are intended to be included directly, they
+must follow the same non-reserved guard naming rule.
