StyleX extraction: computed member access is dropped at the call site

[refirst11]

Using the Devup UI extractor over StyleX source (no StyleX babel or postcss
plugin), static member access resolves but computed member access is dropped at
the call site:

const styles = stylex.create({ base: { display: "inline-block", fontWeight: "500" } });
const colorStyles = stylex.create({ red: { color: "red" }, blue: { color: "blue" } });

<div
  {...stylex.props(
    styles.base,          // ✅ emitted
    colorStyles[color],   // ❌ dropped
    sizeStyles[size],     // ❌ dropped
  )}
/>

Every one of my 1,000 components renders with only the base atoms:

<div class="m n o">

The extraction itself is fine — devup-ui.css contains every variant atom
(.i{color:red}, .s{font-size:12px}, .v{padding:0}, …). They are just never
referenced:

classes defined in devup-ui.css : 34
used in index.html              : 15
never referenced                : 19

So the extractor handles both forms and only the call-site mapping misses the
computed one, which also leaves 19 unused rules in the stylesheet.
