hit 0.3.0

Decouple Flutter layout size from hit-test size, and deliver taps outside parent bounds.

0.3.0

• Narrow the supported public API: package:hit/hit.dart exports widgets and the registry protocol (Hit, HitLayer, HitScope, HitScopeState, HitLink, HitDeferRegistration). Render objects are no longer exported.
• HitScope.of now throws a FlutterError when no scope is found (was assert-only).
• Document deferred opaque semantics: stops further deferred scanning and skips the scoped subtree; document intentional default behavior differences (HitLayer opaque vs Hit.defer/Hit.before translucent).
• Expand tests: Hit.before, nested scopes, explicit outer HitLink, opaque subtree skip, HitScope.of / maybeOf, ClipRect cull, Transform.
• Add GitHub Actions CI (flutter analyze + flutter test).
• Declare supported platforms in pubspec.yaml.

0.2.0

• Fix Hit.defer(paintOnTop: true) with scroll views: deferred paint uses a composited leader/follower so it tracks transforms without a full HitScope repaint.
• Fix disposed-layer crash when reusing paintOnTop follower layers across frames (LayerHandle).
• Expand example app with more demos (Hit.before, resize, window edge, chip, list, slider) and Cupertino UI.

0.1.0

• Initial release: HitLayer, HitScope, Hit.defer / Hit.before, and HitLink.
