//! [`ClientProfile`] construction from live rmcp requests and stored sessions.
//!
//! Server handlers derive the profile from the rmcp request context inside
//! `call_tool`; recovered sessions rebuild it from the `initialize` params
//! persisted in `mcp_sessions`. Both feed
//! [`McpToolExecutor::execute`](crate::McpToolExecutor::execute) so the
//! response builder can shape the wire per client.
