Feature request: opt-in auto-redemption of expiring Codex banked resets #152

Summary

Could onWatch add an opt-in, disabled-by-default setting to automatically redeem expiring Codex banked resets?

The goal is to avoid losing a banked reset simply because the user did not notice its expiry or was away when it needed to be redeemed.

Proposed behavior

• Add an Auto-redeem expiring banked resets setting for each Codex account/profile, separate from the existing quota-starter setting.
• Monitor available banked resets and their expiry times, and redeem the earliest-expiring eligible reset one hour before expiry by default. A configurable lead time would be useful.
• Show the available reset count, next expiry, and last automatic redemption in the dashboard, where that information is available.
• Explain when enabling the setting that redemption consumes a banked reset and can reset the current usage window. Ordinary quota monitoring should remain read-only unless the user explicitly enables this feature.

Reliability and notifications

• Recheck eligibility and current account state immediately before redemption.
• Prevent duplicate consumption across polling cycles, concurrent workers, and restarts. Use API idempotency where supported, and reconcile an uncertain result before attempting another redemption so a timeout cannot consume additional resets.
• Retry transient failures with bounded backoff while the reset is still eligible, respect rate limits, and surface authentication failures that require user action.
• Offer notifications through the configured channels for successful redemption and actionable failures, with enough detail to identify the account and expiry without exposing credentials.
• If an account or API does not expose reset expiry/redemption, show that the feature is unavailable rather than guessing or silently failing.

Related issue

I checked open and closed issues for Codex, reset, banked, and redeem. #76 (Auto quota starter?) is related, but starts ordinary quota windows; this request is specifically about redeeming an existing banked reset before it expires.
