This pull request fixes synchronous Guardrails calls made while an event loop is already running, including notebooks and synchronous helpers invoked by async handlers. Both synchronous clients execute configured guardrails in a scoped worker with copied request context, while retaining the existing idle-loop behavior and tripwire/suppression semantics.

Synchronous Moderation fallback now constructs, uses and closes a native synchronous client inside its worker. Async-client and no-context fallback behavior stays the same. Custom checks that require caller-loop resources should use the asynchronous clients.

Addresses the scenario reported in #131. Includes real SDK contracts for OpenAI/Azure, Chat/Responses, streaming, repeated calls and tripwires, plus a repeated fallback check with a real loopback HTTP connection pool.

Validation: formatting, Ruff, mypy, pyright and the full test suite pass. Two consecutive independent adversarial review rounds were clean.

@codex review

Please review the current head ed4414f. The follow-up replaces a bare Future await in the context regression test with a scheduled asyncio.Event; runtime code is unchanged. Current-head CI and security review pass, and the code-quality feedback is fixed and resolved.

Post-merge validation: merge-queue integration checks passed, and CI on main is also green: https://github.com/openai/openai-guardrails-python/actions/runs/40402499049 .

The docs deployment fails during Setup uv because its cache glob expects an uncommitted uv.lock (No file matched to [**/uv.lock]): https://github.com/openai/openai-guardrails-python/actions/runs/40402499143 . This is the same pre-existing failure seen before this work (https://github.com/openai/openai-guardrails-python/actions/runs/37715113582) and after the preceding release (https://github.com/openai/openai-guardrails-python/actions/runs/40400735123). The docs workflow cache configuration needs a separate follow-up to match tracked dependency files.
