Semantic search across the entire monitored x402 catalog. Given a free-text query (e.g. "weather forecast", "image generation", "EVM gas price oracle"), returns the closest endpoints by advertised purpose. Ranking is deterministic: cosine similarity bucketed to whole percentage points first (80.3% and 80.5% are the same bucket), then trust score, then described-before-undescribed, then endpoint id
