feat(builtins): implement shopt builtin with nullglob enforcement#254
Conversation
Add the shopt builtin for bash-specific shell options: - shopt -s/-u for setting/unsetting options - shopt -q for quiet query (exit code only) - shopt -p for reusable output format - All standard bash shopt option names recognized - Options stored as SHOPT_<name> variables Enforce nullglob behavior: when SHOPT_nullglob is set, unmatched glob patterns expand to nothing instead of keeping the literal pattern. Applied in command args, for loops, and select loops. 8 spec tests + updated builtin count to 94 core (97 total).
