fix: replace jq with node in hooks for Windows compatibility

check-readme.sh and enrich-context.sh used jq for JSON parsing, which
isn't available on Windows. Switch to node inline scripts matching the
pattern used by guard-git.sh and track-edits.sh. Also commit
rebuild-graph.sh which was wired into settings.json but never tracked.
