Set minimum pinch distance to 44

[elliottkember]

Offer sufficiently sized controls. Controls that are too small are hard for many people to interact with and select. Strive to meet the recommended minimum control size for each platform to ensure controls and menus are comfortable for all when tapping and clicking.

Below a certain number of pixels, the math for pinching stops being accurate and the scale starts to do strange things. This PR introduces a minimum distance of 44pt between the fingers for a pinch gesture.

Note

• Pinch-to-zoom stability: Enforces a minimum two-finger distance (~44pt) before applying zoom math to avoid erratic scaling at very small distances.
• Codebase modernization (CJS output): Switches to react/jsx-runtime, adopts class fields and optional chaining, and tidies event-callback wiring without changing public APIs.
• Components/animations cleanup: Updates AnimatedTouchFeedback, StaticPin, and animation helpers to the new runtime and minor refactors; no functional UI changes aside from the pinch threshold.
