  Import shuf utility from OpenBSD

Import the shuf (random permutation) utility from Brian Callahan's
OpenBSD implementation (https://github.com/ibara/shuf).

Features:
- Shuffle lines from stdin or a file
- -e flag: shuffle command-line arguments
- -i flag: shuffle a range of integers (lo-hi)
- -n flag: limit output to N lines
- -r flag: sample with replacement (repeat output)
- -z flag: null-delimited output
- -o flag: write to output file

MidnightBSD-specific changes:
- Use __dead2 instead of __dead for noreturn functions
- Added forward declarations for all functions
- Removed OpenBSD-specific pledge() calls
- Added Capsicum support using caph_enter() from capsicum_helpers.h
- All functions (arc4random_uniform, reallocarray, strtonum, getprogname)
  are already present in MidnightBSD libc

Also added aitools.md documenting GNU coreutils compatibility for AI agents.
