fix(shadcn): invalid postfix ++ on type assertion in ReactShaderToy

[thomasyuill-livekit]

What

Fixes invalid TypeScript on react-shader-toy.tsx:824.

// Before — TS error: operand of ++ must be a variable or property access
gl.uniform1i(timeDeltaUniform, (uniformsRef.current.iFrame.value as number)++);

// After
const frame = uniformsRef.current.iFrame.value as number;
gl.uniform1i(timeDeltaUniform, frame);
uniformsRef.current.iFrame.value = frame + 1;

Why

Unblocks the Vercel build when this component is pulled into web https://github.com/livekit/web/pull/4377.

The original expression applies postfix ++ to a type assertion, which TS rejects since assertions aren't valid l-values.

Notes

• Preserves postfix-increment semantics: pass current frame to the uniform, then increment.
• tsc --noEmit on packages/shadcn passes.
