Add an option for XY pads in Loopy Pro to automatically snap to the center (zero) position when released.

Currently, XY pads stay where they are after you lift your finger. For certain workflows—especially modulation control, filter resets, or effect toggles—it's useful if the XY pad returns to zero when no longer touched, similar to spring-loaded joystick behavior.

— Add a toggle option per axis (X and Y separately) for "Snap to 0 on release"

— Optionally configure the snap-back speed (e.g. instant, or glide back in x ms)

— Optional mode: only snap when released from inside the pad (not from the edge)

✅ Mimics real-world controller behavior (e.g. joystick, spring-loaded fader)

✅ Useful for effects like temporary filter sweeps or dynamic sends

✅ Improves live performance precision

✅ Reduces manual effort to reset control states

✅ Simplifies patch design with fewer extra reset actions needed
