v1.2.0

[1.2.0] - 2026-06-24

Added

• Paint and air/void tools in the block editor — a paint tool with brush,
  recolor and flood-fill modes (with a hover preview ghost and live symmetry),
  plus a void tool and a "Show voids" toggle that reveal the otherwise-invisible
  air and structure_void cells (air in blue, void in red, matching
  Minecraft's show-invisible-blocks colors).
• Tooltip primitive — a richer hover/focus bubble that replaces bare title=
  attributes, portal-rendered so it can't be clipped by the 3D canvas.
• macOS dock icon, and a "Check for Updates…" item under the application menu.

Changed

• Reworked the tooltip implementation.
• Dependency upgrades.

Fixed

• Render blocks taller than two cells correctly.
• Void rendering and the air/void overlay toggle.
