6f83abf786* chore: sync spec-types to modelcontextprotocol@0168c57f Refreshes the vendored schema copies via npm run sync-schema. The draft schema now declares LATEST_PROTOCOL_VERSION = "2026-07-28" (previously the DRAFT-2026-v1 placeholder) and picks up the latest draft doc-comment and type updates. The dated schemas are unchanged. * fix: update the draft wire version to 2026-07-28 The spec repo's draft schema now declares LATEST_PROTOCOL_VERSION = "2026-07-28", but the harness still asserted the old DRAFT-2026-v1 placeholder, so an SDK that sends the version the draft spec actually declares cannot pass the draft suite. - bump DRAFT_PROTOCOL_VERSION in src/types.ts to 2026-07-28 - update the hard-coded literals in tests, example servers, and README - add src/types.test.ts pinning DRAFT_PROTOCOL_VERSION to the vendored draft schema's LATEST_PROTOCOL_VERSION so the two cannot drift, and asserting the draft identifier stays distinct from the dated versions
