v0.2.1-mc26.10

Changed

• Reworked export capture around the RenderDragon scene target and semantic world-submission detection instead of the swap-chain UI target and a draw-count threshold.
• Polished editor and replay-browser scrolling, timeline routing, selection feedback, icon alignment, compact controls, animations, and bilingual labels.
• Preserved the release tag during CI builds so packaged manifests carry the published version.
• Kept the configuration version and recording-file snapshot context version at 1; complete v0.2.0-mc26.10 archives remain compatible and require no conversion.

Removed

• Removed unreachable legacy clip, track, transition, clipboard, menu, hint-bar, curve-editor, and entity-render-hook code.
• Removed periodic camera, entity-pose, and graphics-capture diagnostics from normal rendering and export paths.

Fixed

• Fixed D3D12 exports capturing the UI composition target, which could produce uniform sky-color frames or include the export overlay instead of the world scene.
• Fixed sparse scenes stalling export when world submissions fell below an arbitrary draw-count threshold.
• Fixed the HBUI idle screen appearing in captures while Playback owned input.
• Fixed camera preview stepping backward when native render alpha and replay ticks advanced on different clocks, especially at reduced playback speeds.
• Fixed ordinary observer server synchronization abandoning a parked preview camera after pausing.
• Fixed replay-browser wheel scrolling and crowded timeline labels or click routing obscuring the intended target.
