/**
* Issue #3061 — No-auth providers (opencode / opencode-zen) infinite
* account-fallback loop on a persistent upstream error → unbounded DB growth /
* disk exhaustion.
*
* For a no-auth provider, getProviderCredentials early-returns synthetic
* credentials with connectionId "noauth" BEFORE honoring the exclusion set
* (src/sse/services/auth.ts: the NOAUTH_PROVIDERS block and the opencode-zen
* keyless fallback). So when the chat fallback loop marks the failed "noauth"
* connection and excludes it, the selector hands "noauth" right back → it loops
* forever, writing key-health + request logs every iteration until the disk
* fills (see @paraflu's "failure #320" trace in discussion #3038).
*
* Loop-breaking invariant under test: once "noauth" is in excludeConnectionIds,
* the selector MUST return null (no remaining candidate) so the chat handler
* stops after a single attempt instead of re-selecting the same synthetic
* connection. The happy-path (nothing excluded → synthetic noauth) must stay
* intact so keyless access still works.
