Functions exposed to the LLM to take actions

get_workflow_schemaA	Returns the input schema and webhook details needed to call a given n8n workflow.
execute_workflowA	Executes a tagged n8n workflow through its webhook using the supplied JSON input. Delivery is at-least-once: a timeout or network error does not mean the workflow didn't run, so don't blindly retry on failure.
