fix: exclusive mq boundaries

[Brentlok]

#674

Summary by CodeRabbit

• Bug Fixes

  • Improved responsive layout behavior by ensuring exclusive media-query width boundaries no longer match at the exact boundary value.
  • Applied more precise width handling for strict greater-than and less-than conditions, including viewport-relative widths.

• Documentation

  • Clarified that exclusive media-query bounds use precise numeric handling to exclude equality at the boundary.

📝 Walkthrough

Walkthrough

Native media-query processing now offsets exclusive width bounds by 0.01. Inclusive bounds keep their original values. Native tests cover fixed-width and viewport-relative boundaries.

Changes

Media-query bounds

Layer / File(s)	Summary
Exclusive bound processing packages/uniwind/src/bundler/css-processor/mq.ts, CONTEXT.md	Strict greater-than and less-than operators adjust numeric and expression-based bounds by 0.01. Inclusive operators remain unchanged. The documentation records the generated artifact precision.
Native boundary validation packages/uniwind/tests/test.css, packages/uniwind/tests/native/styles-parsing/media-queries.test.ts, packages/uniwind/tests/native/styles-parsing/meta.test.ts	Tests cover widths below, at, and above 390px, plus pixel and viewport-relative custom bounds. Test runtime metadata now includes screen dimensions.

Summary

This PR corrects native handling of exclusive media-query width boundaries and extends that handling to runtime viewport-relative expressions.

• Applies a 0.01pt offset only to strict greater-than and less-than bounds.
• Preserves runtime evaluation for viewport-relative boundary expressions.
• Adds native tests covering strict and inclusive boundaries and custom width queries.
• Updates compilation-test runtime data and documents the generated artifact’s boundary precision.
