The base Tool class now has an optional `execution` field for storing
task execution metadata (SEP-1686). This lets gateways/proxies preserve
execution info when forwarding tools from backends - previously this
metadata was lost because Tool had no way to store it.
FunctionTool continues to derive execution from task_config as before.

Follow-up to PR #2563 which fixed the signature handling in
create_function_without_params. These tests ensure the fix
works end-to-end for all object types that support Context injection.
* 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
The error messages referenced FASTMCP_EXPERIMENTAL_ENABLE_DOCKET but the
actual setting is FASTMCP_ENABLE_DOCKET.

- Remove _find_referenced_defs method
- Update merging of defs in _merge_schema_with_precedence.
- Adjust tests in test_tool_transform.py to reflect these changes.
Add title parameter to Tool.from_tool() and TransformedTool.from_tool()
to properly inherit or override title field when transforming tools.

Single-element lists like [1] were being incorrectly unwrapped to "1"
in unstructured content while multi-element lists remained as lists.
This created inconsistent behavior where the structure was lost for
single items.
This fix ensures lists always preserve their structure in unstructured
content regardless of length, making behavior consistent and predictable.
Also removes pretty-printing from JSON serialization for more compact
output across tools, prompts, and resources.
