[bug]: Tab crash with skipAnimation and loop

Which react-spring target are you using?

• @react-spring/web
• @react-spring/three
• @react-spring/native
• @react-spring/konva
• @react-spring/zdog

What version of react-spring are you using?

10.0.3

What's Wrong?

When combining a SpringValue that has loop: true and Globals.assign({skipAnimation:true}), there is an infinite loop that crashes the tab.

When setting immediate: true, this infinite loop runs every frame (with the request animation frame loop).

To Reproduce

This minimal code is enough to lock the main thread at 100% usage.

import { Globals, SpringValue } from "@react-spring/web";

Globals.assign({ skipAnimation: true });

new SpringValue(0, {
  to: 1,
  loop: true,
});

Expected Behaviour

If we are setting skipAnimation or immediate, I think the loop parameter should be ignored to avoid this infinite loop.

Start with the minimal @react-spring/web reproduction using SpringValue, loop: true, and Globals.assign({skipAnimation:true}); compare it with the immediate: true behavior described in the issue. Trace the loop and request-animation-frame handling, then verify that the reproduction no longer locks the main thread while skipAnimation or immediate behavior remains intact.
