Performance tip: datapack migration 13.x (#4289)

This is an original write-up for OpenTibiaServers — not copied from elsewhere. Scripts are Lua-only so far; no C++ patches in this branch. Environment: Ubuntu 22.04, 4 vCPU, 8GB RAM, MariaDB 10.11. Is there a cleaner way to validate datapack XML before boot?

For Windows hosts, mark the service recovery options or it will not auto-restart.

Try indexing the player storage lookups; it helped our spawn scripts.

We documented a similar path in our ops notes last month.

Map looks promising. Hunting loop needs clearer signage near the temple.

Thanks — we saw the same spike when market history grew past 500k rows.
