FP's AntiFreecam

🐛 Bug Fixes

• Fixed protection not working for most surface players — a broken effectiveVoidY calculation in the packet handler was setting the hide threshold to Y=-12 for players between Y=15–47, making bases fully visible. Underground blocks are now always hidden correctly at the configured void-y.

• Fixed raycast and move handler fighting each other — when a player dipped just below surface-y, onPlayerMove would deactivate protection instantly, then the raycast task would re-activate it 250ms later, causing rapid state flipping and chunk refresh spam. The move handler now defers to the raycast task inside the raycast zone.

• Fixed eye-Y vs feet-Y inconsistency — the raycast task used eye position (~1.6 blocks above feet) while the move handler used feet position, creating a dead zone where neither system owned the state. Both now use feet-Y consistently.

• Fixed raycast overshoot — the vertical ray was cast surfaceY - eyeY + 2.0 blocks, overshooting past the surface and registering false positives from surface-level blocks.

✨ New

• Raycast deactivation debounce — protection now waits a configurable delay before deactivating when a player leaves the raycast zone, preventing flicker at the boundary. Configurable via protection.raycast.deactivation-debounce-ms (default: 500).

⚙️ Config

• Added protection.raycast.deactivation-debounce-ms: 500 — existing configs are automatically migrated on first load (no manual edits needed).
