Fix AttributeError for functools.partial hooks in Runner Replace direct hook.__name__ access with get_hook_name() utility in _run_hooks function to properly handle functools.partial objects. The get_hook_name utility already exists in prefect.utilities._engine and handles partial objects by checking hook.func.__name__ when the hook is a functools.partial instance. This fix resolves the issue where on_cancellation and on_crashed hooks would fail with AttributeError when using functools.partial objects in flows served via Runner.

Add in_process mode to prefect_test_harness to avoid VCR/httpcore hangs When using prefect_test_harness with HTTP mocking libraries like VCR/vcrpy, nested subflows can hang due to httpcore.PoolTimeout. This happens because VCR wraps httpcore's connection handling and doesn't properly release connections between subflows. This adds an `in_process=True` option that runs the Prefect server in-process using ASGI transport instead of starting a subprocess HTTP server. This completely bypasses HTTP connection pooling, avoiding the VCR issue. Historical context: The subprocess server was introduced in PR #14722 to support WebSockets (required for events). The in-memory ASGI approach doesn't support WebSockets, so this new option is opt-in for backwards compatibility. The implementation uses a ContextVar to avoid backwards imports - testing utilities import from client code, not vice versa.
