Smart onboarding: home profile, tabbed tasks, free app

New onboarding step: "Tell us about your home" with chip-based pickers
for systems (heating/cooling/water heater), features (pool, fireplace,
garage, etc.), exterior (roof, siding), interior (flooring, landscaping).
All optional, skippable.

Tabbed task selection: "For You" tab shows personalized suggestions
based on home profile, "Browse All" has existing category browser.
Removed 5-task limit — users can add unlimited tasks.

Removed subscription upsell from onboarding flow — app is free.
Fixed picker capsule squishing bug with .fixedSize() modifier.

Both iOS and Compose implementations updated.
