fix: disable logging capabilities for stateless servers (#517)

Remove LoggingCapabilities from McpStatelessServerFeatures.Async constructor
as stateless servers do not support setLogging operations. This aligns the
async implementation with the sync implementation which already has logging
disabled.

Follows up on #463
