Resume Execution

Submit a decision for a paused Human in the Loop block and continue the run. Requires write access to the workflow. The body is the resume input, either wrapped in input or sent as top-level fields. The decision is approved unless the input sets _humanInTheLoopDecision (or decision) to denied or rejected. Each resume chooses its own response mode: synchronous by default, Server-Sent Events with Accept: text/event-stream or X-Stream-Response: true, or asynchronous with X-Execution-Mode: async (async wins when both are sent).
