ccae093d1a
Replaces the Client/Server subclassing from the v2 migration with direct Protocol extension, now that the SDK exports Protocol from the client package root. This restores the v1 wire contract on the iframe channel: ui/initialize is the first and only handshake, so deployed hosts keep working unchanged. Deleted with the double handshake: the inner MCP initialize round-trip and its pinned protocol version, the contentless inner capabilities and their retro-registration plumbing, the oninitialized defineProperty shadow, and the getCapabilities/getHostCapabilities split (v1 getCapabilities restored). Tests pin the wire order and assert no MCP initialize is sent in either direction. Note: package.json overrides point the SDK packages at locally built tarballs carrying the Protocol export; replace with published versions before any upstream PR.
