* [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.

Wrap-up for the v0.6.0 release: capture features/BC breaks merged since
v0.5.0 that were missing from documentation.
- CHANGELOG: add the `title` field on `Resource`/`ResourceTemplate` (#301),
a feature plus three positional-argument BC breaks.
- mcp-elements.md: add the missing `title` parameter to the McpTool,
McpResource, McpResourceTemplate and McpPrompt attribute reference
sections; fix a missing closing paren in an `#[McpPrompt]` example.
- server-builder.md: add `title?` to the `addPrompt()` row of the method
reference table (stale since v0.5.0).
- client.md: bump the protocol-version example to `V2025_11_25` to match
the new default.
