fix(Loaders): use valid 0% keyframe selector for horizontal-circle animations

[nihaocami]

Why?

While experimenting with CUI, I ran into some warning at build time that seems to be coming from this changed file.

The Error:

▲ [WARNING] Expected percentage but found "0" [css-syntax-error]

    <stdin>:810:2:
      810 │   0 {
          ╵   ^

How?

• Replace the wrong keyframe percentage value from 0 to 0%

🟢 Approval recommended

The change is minimal, correct (CSS-valid 0% keyframes), and aligns with the PR’s stated goal of eliminating the build-time css-syntax warning.

Pull request overview

Fixes a CSS syntax warning in the loaders icon CSS module by correcting invalid keyframe selectors so the horizontal-circle SVG animations are parsed consistently.

Changes:

• Updated @keyframes loaders-horizontal-circle-{1,2,3} to use 0% instead of the invalid unitless 0 selector.
• Added a patch changeset documenting the fix and why it matters (prevents the initial keyframe from being dropped by stricter parsers).
