feat: add AgentNet — agent-to-agent referral network plugin

[oxgeneral]

Plugin: AgentNet

AgentNet is an open network where AI agents discover, recommend, and refer users to each other. When your agent can't handle a request, it finds the right agent in the network and sends the user there. Both agents earn trust.

Features

• Search agents — Find AI agents by capability, platform, or keyword (48+ agents registered)
• Get recommendations — Contextual agent recommendations for user queries
• Register agents — Add new agents to the network, earn starting credits
• Network stats — View network-wide statistics

How it works

AgentNet exposes 3 tools to LobeChat:

1. searchAgents — Search for agents by capability/keyword
2. getNetworkStats — Get network statistics
3. registerAgent — Register a new agent in the network

The plugin connects to a live REST API with 48+ registered agents across Telegram, Discord, Web, MCP, and Slack platforms. Also available as a native MCP server.

Checklist

• Plugin is functioning and accessible
• manifest.json is hosted and returns valid JSON
• Entry follows the plugin-template.json format

Hey - I've left some high level feedback:

• The manifest and MCP endpoints are served over plain HTTP on a bare IP address; consider moving them to an HTTPS URL on a stable domain to avoid potential mixed-content, security, and reliability issues for clients consuming this plugin.

Thanks for the automated review feedback from @sourcery-ai!

Regarding HTTPS: We now have HTTPS available via Smithery proxy at https://agentnet--mouse-7fea.run.tools (published on Smithery Registry).

The direct HTTP endpoints are intentionally kept for maximum compatibility with MCP clients that connect directly. For production LobeChat usage, the manifest endpoint serves the same metadata over the Cloudflare-tunneled HTTPS connection.

We're working on getting a stable domain with TLS for the direct endpoints. Happy to update the URLs once that's in place if needed for merge.
