feat: engine performance & general other improvements (225 & 244)

[ultraviolet-jordan]

• Fixes Reconnecting while interacting causes moonwalking #22
• Fixes appearance not refreshing on reconnect. Agility users get stuck in agility animation.
• Moves processWorld part of the game cycle to the bottom of the cycle for the next cycle after incrementing the tick, which improves the perceived tick speed/latency to the players. The servers are averaging about ~10ms for processWorld so players will perceive latency to be ~10ms better. No side-effects.
• New INFO WorldStat to track info computing. If someone can hook this up to Grafana that would be good.
• Remove duplicated code by creating the unfocusTargetEntity function.
• Npcs that hunt are doing double lookups to HuntType so I reduced this.
• Stop unnecessarily constructing members npcs and objs on world launch for free worlds.
• Other minor changes.
