DO NOT MERGE: stress-test langsmith flake fix (1000x per matrix)

Temporary experiment branch to validate that removing max_cached_workflows=0
from test_temporal_prefixed_query_not_traced fixes the Windows 3.10 deadlock
flake.

Changes:
- tests/contrib/langsmith/test_integration.py: parametrize the test with
  range(1000) so each matrix entry runs it 1000x via pytest-xdist; remove
  max_cached_workflows=0 from the worker config.
- .github/workflows/ci.yml (build-lint-test job only):
  - Run only the parametrized test with -p no:rerunfailures so a single
    failure is not hidden by retries.
  - Disable poe lint, poe bridge-lint, the time-skipping test step, and the
    openai test step for this branch.
  - Bump job timeout to 60 min.
  - Step timeout 30 min for the stress test.

Success = 0 failures across 10,000 invocations (10 matrix entries x 1000).
Any single failure means the cache=0 removal is not sufficient and a deeper
fix is needed.

This branch will be discarded once CI confirms the result. The actual fix
(test change only, no CI change) will go on a separate branch/PR.
