OpenUI MC 0.0.2

Added

• VirtualGrid for large responsive collections
  • Added row virtualization, responsive column calculation, configurable overscan, scrolling, and stable-key support.
  • Added active-cell, column-count, scroll-offset, and reset APIs for diagnostics and control.
  • Implemented matching behavior for Minecraft 1.20.1, 1.21.1, and 26.1.2.
• Added theme-aware UiRender helpers for surfaces, slots, progress tracks, shadows, and alpha composition.
• Added regression coverage for responsive layouts, virtual collections, theme propagation, Panel color contracts, and container sizing.

Changed

• DynamicGrid now consumes finite available width consistently and calculates multi-row height from the same width.
• Ui.card(a, b, c) now treats Card as a single-content decoration container and automatically stacks multiple supplied children vertically.
• Card elevation now follows Theme.CardTheme.elevated() unless explicitly overridden.
• Panel radius, padding, colors, and elevation now use consistent theme-default and explicit-override semantics.
• Runtime and component-local theme changes now request layout because themes can change spacing and component metrics.
• Virtual collections reuse cells for equal keyed items, rebuild cells when keyed item data changes, and disambiguate duplicate keys by visible index.

Fixed

• Fixed DynamicGrid multi-row measurement, clipping, narrow-width behavior, and child placement.
• Fixed VirtualList and VirtualGrid duplicate keys resolving multiple entries to the same component.
• Fixed virtual collections consuming mouse-wheel input when already at a boundary or when their content cannot scroll.
• Fixed changed keyed data retaining stale renderer-captured content.
• Fixed Card children overlapping when created through the multi-child factory.
• Fixed Card and Panel fluent mutations failing to invalidate paint or layout.
• Fixed default Panel construction becoming transparent after nullable color overrides were introduced.
• Fixed light-theme rendering for Panel, Card, Divider, and reactive text components.

Development

• Updated the README, Getting Started guide, Framework guide, and API Reference for OpenUI MC 0.0.2 and VirtualGrid.
• Added explicit 0.0.2 release documentation and removed accidental editor-specific launch configuration from the release branch.
• Expanded the cross-version test and five-target build gates.
