Note

Low Risk
Test-only setup change with no impact on CLI runtime or production auth paths.

Overview
Adds TEST_SNYK_TOKEN_4 to the TOKEN_ENV_VARS list in test/setup.js, so Jest global setup can pick a fourth optional API token when more than one is defined in the environment.

Behavior is unchanged otherwise: selectRandomToken() still chooses randomly among whichever of the listed env vars are set and non-empty, then configures the CLI for integration tests.
