Fixes

• HitboxEntity dimensions not restored on client spawn — size field stayed at defaults (1.0×0.66) for all joining players, causing visual collision box mismatch with F3+B
• Double HitboxEntity on chunk reload / server restart — onAddedToWorld() spawned fresh hitboxes while NBT-loaded orphans survived, creating duplicate collision proxies
• Component sync packet loss unrecoverable — client could permanently stay in EMPTY-frame limbo (invisible vehicle) with no retry mechanism
• remove() gated behind usesMoreCarsSystems() — if the frame was ever reset externally, hitboxes would leak permanently
• Culling box not updated immediately after setComponents() — relied on next tick's render thread timing (1-3 frame window of potentially incorrect frustum culling)
• Culling box unconditionally recalculated every tick via trigonometric transforms — added position/yaw dirty-check caching

Changes

• onAddedToWorld() now detects NBT-loaded entities and adopts existing hitboxes instead of spawning duplicates
• setComponents() now updates the culling box inline, eliminating the stale-frame window
• remove() now always cleans up hitboxes regardless of frame registry state
• Client-side empty-frame timeout triggers automatic component sync retry after 100 ticks without a successful set
