codex: 0.89.0 -> 0.92.0

- Update Codex from 0.89.0 to 0.92.0.
- Add cmake and git to nativeBuildInputs: rama-boring-sys uses git for patching
  during build.rs and boringssl builds via cmake; without these, local
  aarch64-darwin builds can fail with "No such file or directory".
- Add clang/libclang inputs plus LIBCLANG_PATH and compiler warning flags so
  bindgen can find libclang; keep GCC stringop-overflow and Clang
  character-conversion warning-as-error disabled to avoid known false positives
  in BoringSSL's a_bitstr.cc.
