HoloBuilder 0.1.2

Large schematic display fix.

I forgot to remove a block display limit that was left over from the test version, which could make large schematics look incomplete after loading.

Fixed

• Removed the leftover test display limit from hologram rendering.
• Visible blocks are now selected by render distance instead of by their order in the schematic file.
• Improved rendering performance for very large schematics by using a spatial block index and rendering the nearest visible blocks first.
• Fixed a client crash that could happen when rendering outlines for very large schematics.
• Export now fails with a clear message if the selection contains chunks that are not loaded client-side, instead of silently exporting those areas as air.

Changed

• New exports now use the player's position as the placement reference, so reloading them keeps the schematic offset relative to the player reference point.

Notes

• Export is still client-side only.
• On multiplayer, HoloBuilder can only export chunks that are loaded by the client.
• If the export reports unloaded chunks, move closer, increase render distance, or export a smaller area.
