Remove send_notification_sync() method, notification queue, and background flusher task. Component add/remove operations happen outside sessions and no longer need notifications.
* Implement MCP background tasks (SEP-1686) using Docket
Adds support for background task execution via the MCP task protocol,
powered by Docket for task queue management.
- Tools, resources, and prompts can be marked with `task=True` to run async
- Progress dependency for tracking task progress
- CurrentDocket and CurrentWorker dependencies for advanced use cases
- Client API with `.call_tool(..., task=True)` returns task handles
- Task status notifications via subscriptions
- CLI worker command for distributed task processing
Configuration via environment:
- FASTMCP_ENABLE_DOCKET=true
- FASTMCP_ENABLE_TASKS=true
- FASTMCP_DOCKET_URL=redis://... (or memory:// for single-process)

* Fix tasks example import (TaskStatusResponse → GetTaskResult)
The example was using a non-existent TaskStatusResponse type.
Updated to use mcp.types.GetTaskResult which is what the
on_status_change callback actually receives.

* Fix env var name in Docket error messages

actual setting is FASTMCP_ENABLE_DOCKET.

The on_initialize hook (2.13.0) runs before the MCP session is established, causing request_context
to be unavailable. Changed request_context to return None instead of raising, allowing middleware to
check availability and use HTTP helpers when needed. Updated docs to guide this pattern.
Closes#2393
* Add list_resources, list_prompts, and get_prompt methods to Context
- Add Context.list_resources() to list all available resources
- Add Context.list_prompts() to list all available prompts
- Add Context.get_prompt() to get a specific prompt with arguments
- Update ToolInjectionMiddleware to use new Context methods instead of creating temporary Client instances
- Remove unused Client and FastMCPTransport imports from tool_injection.py
This improves API consistency by allowing middleware/tools to use Context methods directly without needing to create temporary Client instances.
Fixes#2245
