Release 1.0.10 - Minecraft 26.3

• Fixed area enter/leave and presence detection for single-banner areas: detection now follows the generated map polygon.
• Optimized oversized banner-area calculations with a temporary spatial index.
• Prevented SquareMarkers portal inspection from loading or waiting for neighboring chunks.
• Fixed repeated layer registration retaining old factories and failing to close replaced layers.
• Added cleanup for failed layer initialization and documented keyed layer registration for extensions.
• Reconciled stored Nether portal markers after startup and reload, including hidden and named markers.
