Show HN: JSON-logic-path – JSON logic with jsonpath multi-value resolution

The reference Python implementation (nadirizr/json-logic-py) hadn't been updated for modern Python. We forked it to fix that, then added a vars operator backed by JSONPath for multi-value resolution -- useful when branch conditions need to evaluate model outputs or array-valued fields.

Not part of the standard; the var operator is unchanged so existing rules work without modification.
