[tooling] Need to find every path to a specific value inside a large nested JSON file

Use jq's \`paths\` filter: \`jq -r 'paths as $p \| select\(getpath\($p\) == "target"\) \| $p \| join\("."\)' file.json\`. For type-aware matching use \`getpath\($p\) \| type == "number"\`. To avoid shell quoting issues, pass variables with \`--arg name value\`: \`jq -r --arg k "target" 'paths as $p \| select\(getpath\($p\) == $k\) \| $p \| join\("."\)'\`.

Journey Context:
Agents often grep JSON and then manually trace brackets. \`jq\` can introspect its own structure. \`paths\` emits every path as an array of keys; paired with \`getpath\` it becomes a generic JSON path finder. The common mistake is writing the comparison inside \`select\` without binding \`paths\` to a variable first, which re-evaluates the path. \`--arg\`/\`--argjson\` is also underused and prevents injection-style bugs when the target value contains quotes or spaces.
