) After 20+ minutes idle, OAuth tokens expire and subsequent prompts show unhelpful "Error" with no context or retry. This commit fixes the issue across Anthropic and Codex OAuth plugins: - Add 3-attempt retry with backoff for token refresh (network/5xx only) - Fail fast on 4xx auth errors (permanent failures like revoked tokens) - Add 30-second proactive refresh buffer to prevent mid-request expiry - Update `currentAuth.expires` after successful refresh - Classify token refresh failures as `ProviderAuthError` for actionable error messages with recovery instructions - Make auth errors retryable at session level with user-facing guidance - Improve generic `Error` display (no more bare "Error" in TUI) Co-Authored-By: Claude Opus 4.6 <[email protected]>

What does this PR do?
Fixes the issue where leaving altimate-code idle for 20+ minutes causes every subsequent prompt to show just "Error" with no context or recovery path. The root cause is OAuth tokens expiring after idle, and the token refresh throwing a plain
Errorwith no retry logic.Changes:
anthropic.ts/codex.ts: Add 3-attempt retry with exponential backoff for token refresh, fail-fast on 4xx (permanent auth failures), 30s proactive refresh buffer before expiry, fixcurrentAuth.expiresnot being updated after successful refreshmessage-v2.ts: Classify OAuth token refresh failures asProviderAuthErrorinstead ofUnknownError, improve generic Error display (no more bare "Error" in TUI)retry.ts: Make auth errors retryable at session level with actionable user message including recovery instructionsretry.test.ts: Add 8 new tests covering auth error retry, token refresh failure classification, and generic error handlingType of change
