Add --pick flag to gsd-tools.cjs for extracting a single field from
JSON output, replacing all jq pipe usage across workflow and reference
files. Since Node.js is already a hard dependency, this eliminates the
need for jq on systems where it is not installed (notably Windows).
Changes:
- gsd-tools.cjs: add --pick <field> global flag with dot-notation and
bracket syntax support (e.g., --pick section, --pick directories[-1])
- Replace 15 jq pipe patterns across 6 workflow/reference files with
--pick flag or inline Node.js one-liner for variable extraction
- Add regression tests for --pick flag behavior
