Addition of the "AI Agent" action to automations

A new AI Agent action allows you to create autonomous automations capable of reasoning, selecting tools, and making decisions based on the CRM context. Users can write instructions in natural language, use up to 10 tools, enable conversational memory, and retrieve JSON-formatted outputs that can be reused throughout the rest of the workflow. The agent includes ready-to-use templates, detailed execution logs, and several AI models with varying levels of reasoning.
