qxZap/MTLiveMap ? reverse-engineered prompt

Build me the Motor Town live map mod pipeline from this repo.

I want a simple way to add and move custom delivery points, parking spots, garages, gas stations, and fuel pumps in the Jeju world, then package everything into a mod pak I can drop into the game. It should take the data from a JSON file, rebuild the map with the new placements, clone the right in game actors so the game treats them like real delivery points, and support custom cargo and payment tweaks too.

Please make the normal setup as easy as possible, with clear errors if something is missing, and a one command build flow that just works. If the editor side needs a helper script for placing scene markers, include that too. Keep it practical for someone who wants to edit the config, run the build, and launch the game with the changes. If you need current tool or game docs, look them up online.
