The conftest fixtures were saving/restoring the current (potentially
contaminated) values of litellm globals like num_retries instead of
resetting to true defaults. Under xdist, module-level assignments
(e.g. `litellm.num_retries = 3` in 12+ test files) pollute the
shared module state and leak across tests in the same worker.
- Capture true litellm defaults at conftest import time and reset
before each test (local_testing + llm_translation)
- Make llm_translation/conftest.py xdist-safe (skip reload, add
state isolation)
- Replace asyncio.sleep(2) with polling in cooldown handler tests
- Add @pytest.mark.flaky to tests making real API calls under xdist

- Router testing: add CircleCI parallelism=4 with timing-based test splitting
- Guardrails testing: add pytest-xdist -n 4, suppress DEBUG logs with LITELLM_LOG=WARNING
- Rewrite conftest.py in both test dirs for xdist compatibility (save/restore pattern)
- Fix module-level Router instances in test_router_fallback_handlers, test_router_custom_routing, test_acooldowns_router
