Devin AI 703e0f6191 fix: memory leak in execution_spans dictionary ...

Fix memory leak in EventListener where completed/failed tasks were never
fully removed from the execution_spans dictionary. Instead of removing
entries, the code was setting them to None, causing task objects to
remain referenced indefinitely and preventing garbage collection.

Changes:
- Replace 'self.execution_spans[source] = None' with
  'self.execution_spans.pop(source, None)' in both TaskCompletedEvent
  and TaskFailedEvent handlers
- Add comprehensive tests to verify execution_spans cleanup behavior

This fixes unbounded memory growth in long-running processes or systems
executing many tasks.

Fixes #4222
