New Features

Double Spring for Ease-in-out Animation (#250)

Added doubleSpring option to SpringConfig for natural S-curve (ease-in-out) animations.

How it works:

target ← [Leader Spring] ← [Follower Spring] → output

• t=0: Leader starts moving, follower lags behind → ease-in
• t=mid: Both moving at speed
• t=end: Leader settles first, follower catches up → ease-out

Usage:

// Basic ease-in-out
{ stiffness: 180, damping: 22, doubleSpring: true }

// Stronger ease-in (follower has half stiffness)
{ stiffness: 180, damping: 22, doubleSpring: 0.5 }

Improvements

Mobile Animation Easing (#248)

• Changed keyframe easing from linear to ease-in for smoother animation start
• Tuned drill transition spring stiffness values for better mobile feel
