/**
 * Connects to the minimal `createMcpHandler` deployment as both a plain 2025
 * client (`versionNegotiation: { mode: 'legacy' }` — the `initialize`
 * handshake, served stateless from the factory) and a 2026-capable client
 * (`versionNegotiation: { mode: 'auto' }`, served per request). Asserts the
 * same `greet` tool answers identically either way.
 *
 * HTTP-only — `createMcpHandler`'s `legacy: 'stateless'` posture is an HTTP
 * hosting concern; a stdio leg would bypass it. The story body drives BOTH
 * eras itself, so only `url` is read from argv.
