Eingehende Ausloeser: n8n und andere starten Agenten (#725, Stufe 1)

Something outside hands an agent a task - an n8n workflow on a mail, a schedule, a form, or any system that sends an HTTP request. - Core/Triggers/InboundTriggers: one token per trigger and agent, kept as a hash and shown once; a rate per hour; deliveries up to 64 KB. Each delivery becomes a task whose content is framed as foreign content with its origin; every delivery, accepted or refused, is in the audit (source "trigger"). - POST /hooks/trigger on the instance (MCP socket, own token, no browsers); the manager forwards /hooks/{instance}/trigger. /api/triggers to issue, list and revoke. - Agent view: a triggers card with the address and an n8n/curl example. - Nothing writes back: no right to create or change workflows.
