Nathan Price 883a3d19d1 fix(router): hold concurrency semaphore through ttft reconstruction and close stream on exit
The ttft_timeout / stream_idle_timeout path promotes a stream=False call to
streaming and drains it via _collect_stream_with_ttft_timeout. Two correctness
issues are addressed:

- max_parallel_requests semaphore: reconstruction previously ran after the
  'async with rpm_semaphore' block had already exited, so a stream=False caller
  could exceed the configured concurrency for the entire drain. Reconstruction
  now happens inside the semaphore via _await_response, restoring the
  non-streaming concurrency guarantee.

- Connection cleanup: the drain loop now runs under try/finally and calls
  response.aclose() on timeout, cancellation, or normal completion, so a caller
  disconnect mid-reconstruction releases the upstream connection instead of
  leaking it.

The reconstructed ModelResponse now flows through the shared content-policy
check and _track_deployment_metrics, removing the duplicated content-policy
block. The two identical ttft raise sites are collapsed into one.

Tests: semaphore-held-through-reconstruction (fails before the fix),
stream-closed-on-caller-cancellation, and a ttft Timeout tagging
failed_deployment_id so weighted failover / cooldown can exclude the hung
deployment on retry.

Testing for litellm/

This directory 1:1 maps the the litellm/ directory, and can only contain mocked tests.

The point of this is to:

  1. Increase test coverage of litellm/
  2. Make it easy for contributors to add tests for the litellm/ package and easily run tests without needing LLM API keys.
