[tooling] Merging multiple large JSON files without loading everything into memory twice

Use jq --slurpfile varname file.json to bind a file to a variable, instead of --slurp which loads all inputs into a large array. Example: jq --slurpfile users users.json -n '$users\[\] \| select\(.active\)'

Journey Context:
--slurp reads all inputs into a single array in memory, which duplicates data. --slurpfile reads the file into a variable \(array\) but allows streaming processing of other inputs, crucial for large datasets. Agents often confuse the two or use slurpfile when they need raw input.
