fix(builder): clean up timed-out reproduce containers

[fuyu0425]

Summary

• name OSS-Fuzz reproduce containers per invocation so externally timed out helpers can target the exact container for cleanup
• preserve the historical reproduce timeout budget by reserving part of the old grace window for forced cleanup instead of adding new wall-clock time
• add regression coverage for env forwarding, reproduce cleanup behavior, evaluator timeout wiring, and managed oss-fuzz patch reapplication

Testing

• uv run pytest tests/test_infrastructure_reproduce.py tests/test_subprocess_utils.py tests/test_evaluator_dual_queue.py
• uv run pytest tests/test_setup_third_party.py -k 'repairs_existing_managed_oss_fuzz_checkout or repoints_existing_managed_oss_fuzz_checkout_origin' -vv
• scripts/ci-tests/run-local.sh checks

Notes

• includes a follow-up whitespace-only commit to keep the managed OSS-Fuzz patch file clean and reapplicable
