Add replay test fixtures covering the documented flows of the
contributing/samples/models/interactions_api sample (basic text, Google
Search grounding, multi-turn stateful recall, and a custom function
tool), so the sample is exercised by tests/unittests/test_samples.py.
Also fix the shared sample test harness (cli/agent_test_runner.py) to
support the Interactions API:
- Exclude the volatile interaction_id (a server-issued token) and
turn_complete fields from fixture comparison and from rebuilt
fixtures, matching how other non-reproducible fields (timestamps,
usage metadata, etc.) are already handled. The Interactions API
stamps these onto every model response and the replay MockModel
cannot reproduce them.
- Drive all turns of a fixture rebuild on a single persistent event
loop. The sync Runner.run() uses asyncio.run() per call, which closes
the loop the model's cached async api_client is bound to, so
subsequent turns fail with "Event loop is closed" and corrupt
multi-turn fixtures. Reusing one loop keeps the cached client valid
across the conversation.
