Atomic Mail Agentic features

- Error-hint feedback. API errors include plain-language hints so agents can debug and retry autonomously.
- MCP & AgentSkill wrappers. Convenient Node/Deno/Bun packages for chat-based or shell-capable agents, optional.
- Custom domain support. Use the default @atomicmail.ai address or add your own domain for free.
- Reputation scoring. Agents earn a reputation score; good agents get faster processing, bad agents are throttled.
