v0.10.9

Features

• Toggle — Gray arrow icon when toggle body is empty

Bug Fixes

• Drag — Eliminate "wrong block dropped" with multi-layer stale-block defense; block paste, undo/redo, and move shortcuts during active drag; integrate drag-reparent with undo as a single step
• Hierarchy — Reject dangling parentId at universal chokepoint; reconcile remote Yjs reparents; close remaining container drift vectors; exempt Yjs remote sync from dangling parent throw
• Paste — Inherit container parent on replace-insert and x-blok root paste; harden container paste ejection across all container block types
• Callout — Restore plus button and drag handle; stop paste from ejecting children via stale contentIds; prevent Enter from inserting new block inside callout
• Undo — Collapse multi-block paste and alt-drag duplicate into one undo group; eliminate spurious entries from metadata-only writes
• Toolbar — Keep drag handle visible when editing inside table cell
• Insert — Universally protect all Enter paths from nested-block leak
• Table — Tighten list item spacing inside table cells
• Yjs — Map 'no-capture' origin to local to prevent mid-op sync clobbering tool state

Maintenance

• Yjs — Make DocumentStore.ydoc private; enforce local origin whitelist with exhaustive mapper
• CI — Shard E2E tests via reusable workflow; add merge-reports job; run spec-file coverage validator on every PR; remove size-limit bundle size check
