CRITICAL: Disabling all OAuth/OIDC checks via checks: [] may weaken auth security

In NextAuth, checks controls protections like state / pkce / nonce (provider-dependent). Setting this to an empty array disables those validations and can open up CSRF / auth-code injection style risks. If this is required for WorkOS compatibility, please add a rationale (and ideally scope to the minimal required checks) rather than disabling all checks.
