🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Assert that the replacement middleware is installed.

The assertion at Line [230] proves only that _summarization_event is absent. It also passes if the implementation removes the built-in middleware and ignores _ReplacementSummarizationMiddleware. Add a unique state key or observable hook to the replacement, then assert that marker is present or invoked together with the absence check.

As per path instructions: Tests should cover the behavior promised by the changed API surface and prefer assertions on middleware ordering over shallow smoke tests.

In `@python/tests/integrations/deepagents_tests/test_deepagents_integration.py`
around lines 218 - 230, Strengthen the test around create_deep_agent and
_ReplacementSummarizationMiddleware by adding a unique state channel or
observable hook to the replacement, then assert that it is installed or invoked
while retaining the _summarization_event absence check. Prefer verifying the
middleware ordering or resulting middleware state so the test distinguishes
replacement from simply removing the built-in middleware.
