feat: add Helixa AgentDNA action provider — onchain identity for AI agents

[Bendr-20]

Summary

Adds HelixaActionProvider — onchain identity and reputation for AI agents on Base via the Helixa AgentDNA protocol (ERC-8004 compliant).

Problem

Every AI agent that gets a wallet needs an identity. A wallet is just a keypair — it does not tell you WHO the agent is, what it does, what framework it runs on, or what its reputation looks like. There is no standard way for AgentKit agents to establish onchain identity.

Solution

Helixa AgentDNA provides ERC-8004 compliant identity NFTs on Base. This action provider lets any AgentKit agent:

Action	Description
register_agent	Mint an onchain identity NFT (+ optional .agent name)
get_agent	Look up agent by token ID
get_agent_by_address	Look up agent by wallet address
mutate_agent	Record version changes
add_trait	Add personality traits and skills
resolve_name	Resolve .agent names to addresses
check_name	Check .agent name availability
get_helixa_stats	Protocol statistics

Usage

import { helixaActionProvider } from "@coinbase/agentkit";

const agentkit = await AgentKit.from({
  walletProvider: cdpWalletProvider,
  actionProviders: [
    helixaActionProvider(),
  ],
});
