ComposeA11yScanner 2.1.0

This release introduces rendered text-contrast analysis and improves scanning reliability across Compose-only and Fragment-based applications.

Highlights

Added TextContrastRule with screenshot-based analysis of rendered text and background colors.
Added support for detecting insufficient text contrast that cannot be determined from the Compose semantics tree alone.

Improved Compose host selection, including applications with nested ComposeView instances.
Improved scanning across Fragment and Compose screen transitions.
Fixed stale results appearing after navigation.
Improved screen identity and readiness detection.
Fixed scans occasionally returning 100% before the active screen was ready.

Reduced false-positive text-contrast warnings for rich text and code blocks.
Fixed duplicate-description detection for repeated actions inside collections.
Reduced duplicate-description false positives caused by parent/child semantics copies.
Fixed missing-content-description warnings for zero-sized and off-screen nodes.
Improved focus-order handling for:
- Zero-sized nodes
- Lazy and reverse layouts
- Elements belonging to different semantic containers
Reduced false-positive touch-target-overlap warnings.

No breaking public API changes.
Existing integrations remain source-compatible with version 2.0.0.
Because TextContrastRule is enabled, applications may receive new accessibility warnings that previous versions could not detect.
