Vacuum, weight and Health import

What's new

• Stomach vacuum: a guided breathing timer where the phone "breathes" with you — the haptics swell on the inhale and fade on the exhale. It's a ritual, not a streak workout: it doesn't extend your streak, but directly trains Core.
• Indoor mode: walk and run tracking without GPS — distance from your steps, for treadmills, gyms or areas with signal jamming.
• Profile: height, date of birth and sex — for more accurate step-based distance and calories.
• Weight history: a chart and trend right in Analytics — points come from Apple Health (smart scales) or manual entry.
• Two new camera-tracked exercises: burpees and lunges — counted automatically, just like push-ups and squats.
• Workouts recorded outside the app (say, by another tracker) are now pulled in automatically from Apple Health — with a heads-up if it leveled you up.
• During indoor workouts, the watch now streams cadence, steps and distance to the phone too.
