[Demo] HabitSync - Cross-device habit tracking with social accountability

The accountability partner feature is what makes this different. I'd use this with my co-founder for daily standups too.

Cross-device sync is a must-have. I start my morning on my phone and work on my laptop. Most habit apps are phone-only.

Web app is functional! Cross-device sync via Firebase is working smoothly. Starting on the accountability partner feature this week.

Making progress on the web app! Mobile apps (iOS/Android) coming after the web version is solid.
