Builder Tool addition

• Title: cardano.delivery
• Description: Webhook service that sends HTTP notifications for Cardano events, including transactions, blocks, delegations, epochs, governance actions, and more, filterable by address, amount, and policy ID.
• Category (pick exactly ONE): api
• Properties (language + interface):
  • Language: none (hosted service, no client library)
  • Interface: webhooks, agentic: new property values, added to InterfaceProperties in src/data/builder-tools/tags.js because the existing set (rest/graphql/grpc/websocket) doesn't describe a push-based webhook delivery model or its no-account agentic mode for autonomous agents.
• Website: https://cardano.delivery/
• Repository: null (closed/hosted service)
• Docs: https://cardano.delivery/docs/
