e4a8a224ff* [Client] Add client-side elicitation support The SDK could send elicitation/create requests from a server tool via ClientGateway::elicit(), but the client could not receive them: there was no request handler, and ElicitRequest was not registered in MessageFactory, so incoming elicitation/create messages failed to parse. This adds the client half, mirroring the existing Sampling pattern: - Register ElicitRequest in MessageFactory so elicitation/create parses. - ElicitationRequestHandler wraps a user callback and returns an ElicitResult (accept/decline/cancel) or an Error. - ElicitationCallbackInterface defines the callback contract. - ElicitationException forwards a specific message to the server; any other throwable returns a generic error. Includes unit tests, a runnable client example against the elicitation demo server, and client docs/README updates. * [Client] Simplify elicitation example labelFor() per review Type the parameter as AbstractSchemaDefinition and read ->title directly instead of matching on each concrete definition type. title is a required non-null string on the base class, so the match and the $name fallback were redundant.
