fix(javascript): ignore async exec stdio options (#7087)

Respect Node asynchronous exec/execFile method-default stdio instead of interpreting an ignored option. Remove the superseded callback-shape query while preserving caller input, Evidence, uncertainty, argv and fork controls. Independently validated on current main through actual Node pipe capture, matching real-app CLI/MCP facts, 81 targeted tests and static checking. Closes #7217.
