Converts msg.stream into msg.payload messages. Non-streaming messages pass through unchanged.

Modes

Per-chunk default
One output message per token, sent immediately. Adds msg.streamChunkIndex.
Accumulator
Collects all chunks, sends a single msg.payload when the stream ends. Adds msg.streamChunkCount.

Comma-separated msg property paths (e.g. transcript, content.text). The accumulated text will be written to each path in addition to msg.payload.
