🎉 New Features:

Smart Auto Pregen: Lon now intelligently pre-generates chunks in the player's view direction as you move. Default is ON. Toggle with /lon autopregen on/off.

Network Ping: /lon ping displays your connection latency in milliseconds with color-coded feedback.

Entity Cleanup: /lon entities clear safely removes all dropped items (except XP orbs) to quickly reduce lag.

Memory Pressure Warning: HUD memory line now changes color dynamically:

🟢 Green: safe (<60%)

🟡 Yellow: warning (60-80%)

🔴 Red: high pressure (80-90%)

🔴⚡ Flashing Red: critical (>90%)

⚡ Improvements:

Entity overload warning now includes a direct suggestion to use /lon entities clear.

HUD automatically hides when the F3 debug screen is open, preventing overlap.

🔧 Technical Changes:

Auto pregen uses player's view cone (FOV 120°) to generate only visible chunks, saving CPU and memory.

Memory color logic fully client-side, zero server impact.
