Prepend custom jq definitions to every filter to patch jaq limitations: - setpath(p; v): recursive path-setting, not in jaq stdlib - leaf_paths: paths to scalar leaves via paths(scalars) - match: adds "name":null to unnamed captures (jaq omitted it) - scan: uses "g" flag for global matching (jq default behavior) The // alternative operator on null remains skipped (jaq core limitation). Enable 4 previously-skipped spec tests. Skip count: 18 -> 14. Closes #328 https://claude.ai/code/session_01QbjrsMFJbHy5XfHCzA6TjM
