commit d05d00966b605a8bbb2d3fb2856c5233ecdefcb2
from: Brett Fisher <code@brettfisher.xyz>
date: Thu Jun 18 05:20:29 2026 UTC

bxnotify.c: Document full option set and ensure portable getopt declaration.

  - Include <getopt.h> to provide an explicit, portable 
    declaration for the getopt(3) function. This aligns with 
    the code correctness and portability goals across 
    ARM64, AMD64, and RISC-V architectures.
  - Update the usage error message in the getopt default case
    to include the [-C border] option, which was previously
    omitted from the help text despite being a valid flag.
