chore(deps): bump tornado from 6.5.4 to 6.5.5 (#21311) Signed-off-by: dependabot[bot] <support@github.com> Co-authored-by: dependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com>

Convert maintain_concurrency_lease to class-based context manager On CPython 3.13, PyThreadState_SetAsyncExc-injected exceptions can escape generator-based context managers because gen.throw() does not reliably deliver the exception to the generator's except handler. By using a class-based context manager, _LeaseRenewalInterrupt is caught directly in __exit__ without going through generator throw() machinery.

Replace task runner with lightweight stand-in in with_context When hydrating context in a subprocess, the original flow's task runner (e.g. ProcessPoolTaskRunner) would be duplicated and started, which fails inside daemonic workers and wastes resources. Replace it with a minimal ThreadPoolTaskRunner since with_context only needs run metadata for logging, not task submission. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Fix CI failures: server lease_duration validation and Python 3.13 async exc Integration tests used lease_duration=2 which the server rejects (ge=60). Fix by keeping lease_duration=60 and mocking _RENEWAL_FRACTION to 0.01 so renewals still happen quickly in tests. On Python 3.13, _LeaseRenewalInterrupt can fire at any bytecode boundary in the finally block (not just during thread.join). Wrap the entire finally body in try/except _LeaseRenewalInterrupt to handle this. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
