/* AdrOS wait status encoding:
 *   Normal exit:  exit_status = code  (from _exit(code))
 *   Signal kill:  exit_status = 128 + sig
 *
 * We provide Linux-compatible macros that work with AdrOS's simple encoding.
 * Since AdrOS passes exit_status directly (not Linux-style packed), these
 * macros approximate the behavior:
 *   - exit code 0..127 → normal exit
 *   - exit code 128+   → killed by signal (128+sig)
