60711951d4* [Schema][Server] Add the extensions framework SEP-2133 defines enableExtension() took any string and advertised it, with no way for an extension to add a method: MessageFactory could not decode one, so nothing downstream ever saw it. Identifiers are now checked against the _meta key naming rules through ExtensionIdentifier - a prefix is mandatory, since an unprefixed name has no owner, and the modelcontextprotocol/mcp second labels the specification reserves are recognised. An extension implementing MethodProvidingExtensionInterface contributes both its message classes and the handlers serving them. MessageFactory::make() takes an $additional list of message classes, and RequestHandlerInterface's result template is covariant so a handler declaring a concrete result satisfies a collection typed by the interface. * Fix stale @see reference in MethodProvidingExtensionInterface docblock * [Schema][Server][Client] Make ExtensionIdentifier a value object ExtensionInterface::getId() now returns ExtensionIdentifier, which validates the SEP-2133 naming rules at construction instead of the callers checking it. getMessages()/getRequestHandlers() move into ExtensionInterface itself; AbstractExtension gives them empty defaults for extensions that only announce a capability.
