feat: add QuotaUsed/QuotaResetAt to Provider for restart persistence#63
Conversation
Quota state (bytes consumed and period reset deadline) is now exposed via ProviderStats and can be restored on restart by setting QuotaUsed and QuotaResetAt on the Provider config. No library-side persistence is needed — callers read Stats() before shutdown and pass the values back on the next run. Also rewrote README with comprehensive examples, expanded API reference, and a dedicated quota management section showing the save/restore pattern.
