* Add modern-era (2026-07-28) test-server preset (#1700) The era-aware connection model (#1626, PR #1697) added per-server `protocolEra` and the era-aware Connection Info UI, but no bundled test server negotiated the modern era — the modern happy path had only unit/Storybook fixtures, no live coverage. Serve the modern (2026-07-28) protocol era from the HTTP test server via the SDK's `createMcpHandler`. A `modern` flag on `ServerConfig` (and a `transport.modern` field in the JSON config) mounts the handler with a dual-era `legacy: "stateless"` fallback by default, or `legacy: "reject"` for modern-only strict serving. The web-standard `fetch` handler reuses the existing `toWebRequest`/`writeWebResponse` conversion, so no new `@modelcontextprotocol/node` dependency is needed. An SDK v2 client negotiating `protocolEra: "auto" | "modern"` now reaches the modern leg end-to-end: `getProtocolEra() === "modern"`, `getNegotiatedProtocolVersion() === "2026-07-28"`, and a populated `getDiscoverResult()`. Verified live in the Inspector — Connection Info shows Era Modern / Session Sessionless / the Discovery section. - Modern serving path + `listen`/`startModernHttp` helpers in test-server-http.ts; modern-leg teardown in stop(). - `modern` config field threaded through load-config/resolve-config with a streamable-http-only validation guard; modern-http.json demo config. - Integration test covering auto/modern negotiation, the dual-era legacy fallback, a modern tools/call, and the strict `legacy: "reject"` rejection.

Gate on truthiness instead of `!== undefined` so only *enabling* modern on a non-HTTP transport is rejected.
