// Package zip wires the unified ads engine as a first-class plugin for api.hanzo.ai
// (/v1/ads and /v1/ad) using the ZIP framework (github.com/zap-proto/zip).
//
// By declaring operations as TYPED ops on the ZIP router, every operation
// automatically projects to:
//   - An OpenAPI 3.1 operation with full schemas and parameter contracts
//   - A native Model Context Protocol (MCP) tool accessible to Claude, Cursor, and ChatGPT
//   - A native CLI command group (hanzo ads ...)
//   - Typed SDK methods across Go, TypeScript, Python, and Rust.
