feat: add Maiat Trust Score plugin

[JhiNResH]

Maiat Trust Score Plugin

Adds trust score verification to GAME agents via Maiat Protocol — an on-chain trust layer for agentic commerce on Base.

Why this plugin matters

AI agents executing autonomous swaps face a real risk: they can't inherently tell if a token is a rug, honeypot, or scam. Maiat provides verified trust scores from:

• On-chain activity analysis
• AI-verified community reviews
• TrustScoreOracle contract on Base Sepolia

Functions

Function	Description
check_trust_score	Query trust score (0–10) for any address or project name
gate_swap	Check both sides of a swap before executing — rejects if below threshold
batch_check_trust	Score up to 10 addresses at once, ranked by trust

Usage

import MaiatTrustPlugin from '@virtuals-protocol/game-maiat-plugin';

const plugin = new MaiatTrustPlugin({ minScore: 3.0, chain: 'base' });

const agent = new GameAgent(GAME_API_KEY, {
  goal: 'Execute swaps only for tokens with trust score ≥ 3.0/10',
  workers: [plugin.getWorker()],
});

Technical

• Zero external SDK dependencies (pure fetch calls to Maiat REST API)
• TypeScript + CJS/ESM dual build
• Follows same structure as coingeckoMaopPlugin
• API is free tier (100 req/day), optional API key for unlimited
