What
The self-hosted runner's inference-token auto-refresh logic was rewritten. It now tracks the token's time-to-live (ttlMs, 30 minutes by default), and retries failed refreshes with exponential backoff plus jitter (a random delay) instead of a fixed interval.
Tokens nearing expiry get a separate, shorter retry window (expiredRetryMs).
A new error classifier distinguishes errors worth retrying from ones that aren't: a new RemoteConfigWithoutInferenceAuthError, or an HTTP 401/403, is treated as non-network and not retried early.
A new onResultApiError callback lets a 401/403 returned by the model API during a child session's turn trigger an immediate, out-of-band token refresh (refreshNow()) instead of waiting for the next scheduled refresh.
Why
This makes token refresh more resilient to transient failures while reacting immediately to real auth failures, so a self-hosted runner recovers faster from an expired or rejected inference token instead of a child session stalling until the next scheduled refresh.
