[tooling] jq runs out of memory or is too slow when processing multi-gigabyte JSON files

Use \`jq --stream\` to process JSON documents incrementally, emitting \[path, value\] pairs without loading the entire file into memory

Journey Context:
Standard jq loads the entire JSON document into memory as a data structure, which fails for large files \(e.g., logs, database dumps\). The --stream flag parses JSON in a streaming fashion, outputting \[path, value\] pairs incrementally. This allows processing files of any size with constant memory usage. The tradeoff is a more complex query syntax—you work with paths and values rather than the full structure, often using \`fromstream\` to reconstruct objects selectively or filtering the stream with \`select\`. For very large files, this is the only viable approach.
