Some checks are pending
CI / build (push) Waiting to run
## Summary - Adds KOReader progress sync integration, allowing CrossPoint to sync reading positions with other KOReader-compatible devices - Stores credentials securely with XOR obfuscation - Uses KOReader's partial MD5 document hashing for cross-device book matching - Syncs position via percentage with estimated XPath for compatibility # Features - Settings: KOReader Username, Password, and Authenticate options - Sync from chapters menu: "Sync Progress" option appears when credentials are configured - Bidirectional sync: Can apply remote progress or upload local progress --------- Co-authored-by: Dave Allie <dave@daveallie.com>
