[tooling] JSON output is hard to parse in shell pipelines

Use jq as a typed query language: \`jq -r '.items\[\] \| select\(.status == "open"\) \| .id'\` extracts raw IDs; \`jq 'del\(.metadata\)'\` removes keys; \`jq 'paths'\` shows the shape of nested objects.

Journey Context:
Agents often pipe JSON through \`grep\`/\`sed\`/\`awk\`, which breaks on escaping, arrays, and nested objects. jq treats JSON as structured data. The \`-r\` flag is critical when feeding IDs or URLs into the next command, otherwise strings come wrapped in quotes. \`select\(\)\` filters; \`del\(\)\` prunes; \`paths\` and \`getpath\` navigate unknown schemas. A common mistake is using \`jq .\` in scripts — it pretty-prints, which can change field order and break downstream diffing. Use \`jq -c\` for compact, stable streaming output in pipelines.
