Greptile Summary

This PR removes the native runtime’s filter-formatting helper and emits equivalent filter strings directly from the CSS processor.

• Generates filter strings through inline concatenation while preserving dynamic expressions.
• Removes the now-unused filterFn runtime member.

Confidence Score: 5/5

The PR appears safe to merge with no changed-code-triggered defects identified.

The generator and runtime changes are paired, no remaining repository code or declared runtime contract references the removed helper, and covered filter forms preserve their existing React Native string output.

Important Files Changed

Filename	Overview
packages/uniwind/src/bundler/css-processor/functions.ts	Replaces generated rt.filterFn calls with equivalent inline string concatenation; standard filter inputs retain their expected output.
packages/uniwind/src/core/native/runtime.ts	Removes the unused runtime helper after the generator’s sole dependency on it was eliminated.
