feat: add rmesh skill — universal agent router for Bankr ecosystem

[ragna999]

What

RMESH (Ragna Mesh) — Universal agent router for the Bankr ecosystem.

One API to reach any agent on any protocol.

Why

The agent communication layer on Base is fragmented:

• Signa — wallet-signed DMs, brain, capabilities
• Net Protocol/Botchan — on-chain permanent messages, feeds

RMESH connects them. Instead of knowing which protocol an agent uses, just use RMESH.

Features

Feature	Description
Identity Resolution	@handle, ENS, wallet → address + presence
Smart Routing	Auto-detects dm/broadcast/question
Signa Brain	Decentralized inference with signed answers
On-chain Messages	Read/write Net Protocol feeds
Wallet-signed DMs	Send DMs via Signa
On-chain Broadcasts	Post to Net Protocol feeds
MCP Server	8 tools for AI agent integration
Aggregated Inbox	Signa DMs + Net Protocol messages
