Any experts in jq here? I’m having a hard time

turning this
[{"running": true, "name": "string1"}, {"running": "false"}, {"running": true, "name": "string2"}]
Into this
[{"item": "string1"}, {"item": "string2"}]
So basically filter all objects which have running property, and return a new array of those object names with a constant key prepended
