CircadiaOS: Sleep Tracker

This version adds a referral program. Users receive a personal referral code, and when three invited friends create an account and connect a wearable device, the referrer is issued an App Store offer code redeemable for one free month of Premium. All rewards are fulfilled through Apple's offer code system — no subscription content is unlocked outside of StoreKit, and no referral code applies a discount or grants entitlement within the app.

Also included: a prompt asking users to rate the app, shown at most once per version using SKStoreReviewController; fixes to label overlap on the nightly schedule chart; and a fix restoring notification scheduling for users who completed the new setup flow.

No changes to pricing or subscription terms.

Full functionality requires pairing a smart thermostat and a wearable device. The demo account has representative data pre-populated so the core experience can be reviewed without hardware.
