Class Nexus\Mcp\Schema\ClientCapabilities

`final`
`readonly`
`implements`	`JsonSerializable, Arrayable<array{experimental?: array<string, object>, roots?: object{listChanged?: bool}, sampling?: object, elicitation?: object}>`

Capabilities a client may support. Known capabilities are defined here, in this schema, but this is not a closed set: any client can define its own, additional capabilities.
