build: add -Wtrailing-whitespace=any
This is available in GCC 15. See
https://gcc.gnu.org/gcc-15/changes.html.
What changed, and why it matters
This commit adds a new compiler warning flag that flags trailing whitespace in source code. It is a code-style/build-hygiene change, not a security fix. There is no vulnerability being patched.
No security action required; treat as a routine build-system cleanup.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The change appends -Wtrailing-whitespace=any (GCC 15+) to the warn_interface target in CMakeLists.txt via try_append_cxx_flags, which only enables the warning if the compiler supports it. It does not alter runtime behavior, fix a bug, or address any reported security issue.
