Module context 

Request context for MCP handlers.

The context provides access to the current request state and allows handlers to interact with the connection (sending notifications, progress updates, etc.).

Key Features

• Borrowing-friendly: Uses lifetime references, NO 'static requirement
• Progress reporting: Send progress updates for long-running operations
• Cancellation: Check if the request has been cancelled
• Notifications: Send notifications back to the client via Peer trait

Example

use mcpkit_server::{Context, NoOpPeer, ContextData};
use mcpkit_core::capability::{ClientCapabilities, ServerCapabilities};
use mcpkit_core::protocol::RequestId;

// Create test context data
let data = ContextData::new(
    RequestId::Number(1),
    ClientCapabilities::default(),
    ServerCapabilities::default(),
);
let peer = NoOpPeer;

// Create a context from the data
let ctx = Context::new(
    &data.request_id,
    data.progress_token.as_ref(),
    &data.client_caps,
    &data.server_caps,
    &peer,
);

// Check for cancellation
assert!(!ctx.is_cancelled());
