GriefPrevention3D v17.4.7

Wiki: https://github.com/castledking/GriefPrevention3D/wiki

Highlights

• New INITIALIZE_ZONE_3D visualization — First-click diamond markers for 3D admin claims and 3D subdivisions now render at the exact clicked Y coordinate instead of snapping to the terrain surface.
• Proper visualization pipeline — Replaced a raw sendBlockChange hack with a real visualization type that supports cleanup tracking, glow mode, and event firing.

INITIALIZE_ZONE_3D Visualization

3D claims are placed at the exact block the player targets — that's the core difference from 2D claims, which snap to terrain. Previously, the first-click diamond marker didn't respect this: it either used INITIALIZE_ZONE (which terrain-snaps to the surface) or bypassed the visualization system entirely with a raw sendBlockChange.

The new INITIALIZE_ZONE_3D type renders the diamond marker at the exact Y of the clicked block. It routes through drawRespectingYBoundaries in FakeBlockVisualization and uses exact placement in GlowingVisualization, consistent with how SUBDIVISION_3D and ADMIN_CLAIM_3D boundary types already work.

Both 3D admin claims and 3D subdivisions now use this type for their first-click marker.
