v0.14.0

Features

• Columns — New side-by-side layout tool (#67). Create 2–5 column presets from the toolbox, or drag a block beside another to spawn a column. Drop anywhere left/right of a block to make a new column, or into a column body to stack inside it. Columns nest, auto-unwrap when emptied, and stack vertically on narrow viewports.
• Columns — "Turn into columns" command wraps a multi-block selection into a column layout, available from the Convert-to menu.
• Columns — Hover-revealed resize separators between columns: drag to resize, keyboard-resizable with ARIA slider semantics, double-click a divider to equalize widths.
• Columns — Horizontal arrow keys traverse between sibling columns; new columns animate in Notion-style.
• Inline Toolbar — Appears instantly on selection release, no animation delay.

Bug Fixes

• Inline Toolbar — Removed entry animation that delayed appearance.

Maintenance

• i18n — Column resize aria-labels and turn-into-columns strings across all locales.
• CI — Repair unit tests, e2e merge, and mirror push on master; mirror push works for both branch and tag events.
• Tests — Exhaustive block-in-column compatibility suite, live-drag lifecycle specs for every block type, multi-select block-settings header i18n regression.
• Playground — Columns example in the editor demo and block-states gallery.
