> The camel-jbang monitor sends actions through the shared <pid>-action.json / <pid>-output.json pair, and deletes the output file before and after each of its actions (MonitorContext.executeAction). A client asking the same integration at the same moment (a camel command, a script, an agent in the monitor's AI panel) loses its answer or reads the monitor's. Found while measuring CAMEL-25438: the monitor deleted the answer of the measuring script.
> Since 4.21 the connector also takes <pid>-action-<requestId>.json and answers in <pid>-output-<requestId>.json (RuntimeHelper, used by camel ask and the MCP server).
> Proposal: the monitor uses the per-request files.
> * No client can lose another's answer.
> * The connector answers every pending action file in one loop, so the monitor can drop its one-action-at-a-time lock per integration: several tabs' actions are answered together in one loop instead of one loop each (with the faster connector loop, about 0.1 s).
> * Fallback: the monitor attaches to any running integration, and a connector older than 4.21 only knows the shared file: use the Camel version of the status file to pick the protocol.
