Research direction

Start by inspecting the FreeBSD bindings in libc and the use of KINFO_FILE_SIZE at crates/fs/src/fs.rs:347. Compare the available architecture-specific definitions, then confirm that the gram-text-editor-3.3.0 FreeBSD build compiles successfully on arm64 without the missing-value error.
