Bug: The global installedIntegrations array is not reset between tests, causing setupOnce() to be skipped in the second test, which prevents channel subscribers from being registered and leads to test failure.
_{Severity: MEDIUM}

Suggested Fix

The global state needs to be reset between test runs. The installedIntegrations array should be cleared as part of the test teardown or setup process. For example, the resetGlobals() function could be modified to also clear this array, ensuring each test runs in an isolated environment and setupOnce() is called correctly.

Potential issue: The integration test suite contains two separate tests that both call
`init()`. The first test populates the global `installedIntegrations` array. Because
this array is not reset between tests, the second test's call to `init()` finds the
integration is already present in the list. This prevents the `setupOnce()` function
from running during the second test. As `setupOnce()` is responsible for registering
subscribers to the `orchestrion:openai:chat` channel, no subscribers are registered for
the second test. Consequently, when the test publishes events to this channel, there are
no listeners, causing the test to fail its assertions for created spans.
