Subject: [PATCH] Implement complete Nim clone of picoclaw
- Full translation of PicoClaw from Go to Nim.
- Highly optimized for performance and low memory consumption using Nim's ORC and async architecture.
- Modular design with support for multiple LLM providers, tools, and communication channels.
- Fully self-contained single binary implementation.
- Support for Telegram, Discord, WhatsApp, and more.
- Built-in scheduler and heartbeat services.
