v0.0.8 - Call graphs for completed slow tasks

🔭 Call graphs survive task completion

zuvloop 0.0.8 keeps slow-callback telemetry useful when the blocked callback is the final step of a coroutine.

pip install zuvloop==0.0.8

• Completed slow tasks retain their identity in the asyncio.call_graph span attribute instead of falling into the no-call-graph bucket (#98).
• The fallback matches the shape of asyncio.format_call_graph() and includes the task name, completion state, coroutine qualname, and source location.
• Task results and exception messages stay out of telemetry. The fallback renders controlled metadata instead of the task repr, which may contain application data.
• Active tasks keep the full standard-library call graph. The fallback only applies after Python has released the completed coroutine's frames.
