Test cleanup of a command with output.

Extend the release cleanup test with an open command_execution item containing output. Assert that release interrupts it and preserves the output. The dynamic_tool fixture cannot catch a regression that excludes commands or breaks their payload comparison.

679 - 689:
Extend the release cleanup test to cover an open command_execution item with
output. Assert that release interrupts the command and preserves its output,
exercising the payload comparison used by writeIfStoredPayloadMatches rather
than relying only on the dynamic_tool fixture.

After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr
