Require self-describing 2026-07-28 requests and expose server discovery so callers no longer depend on initialization state. Return cache and result metadata required by the new wire contract, and reject legacy or malformed requests with actionable errors. Co-Authored-By: HAL 9000
Send modern request metadata from the live test harness and replace the legacy initialization check with server discovery coverage. Verify cache and server metadata on discovery, listing, and live tool responses so the stateless wire contract is exercised against a node. Co-Authored-By: HAL 9000
Describe the required per-request metadata and discovery flow so MCP clients use the server without the removed initialization handshake. Call out the latest-only compatibility boundary and supported stdio method surface. Co-Authored-By: HAL 9000

Alternative to #255 (which I only saw after opening this).
Here we don't keep the old version around, just go for the new thing.
(cc @benthecarman let me know what you prefer).
