Module handler 

Client handler traits for server-initiated requests.

MCP servers can initiate certain requests to clients, such as:

• Sampling: Request the client’s LLM to generate a response
• Elicitation: Request user input through the client
• Roots: Get file system roots that the client exposes

This module defines traits that clients can implement to handle these requests.
