Add custom MLO maps and interiors

MLOs (interiors and intersections built with OpenIV) and custom maps install as streaming resources. Their main challenge is frequent conflicts between resources that edit the same building or map cell.

Cause / The problem

An MLO fails to load, flickers or causes FPS drops when two resources stream the same ymap or ytyp, when _manifest.ymf is missing, or when the ensure order places the resource before its dependencies. The server cache can also keep an old version of the files.

Solution

1. Create a resource folder, e.g. resources/[mlo]/my_interior/, with an fxmanifest.lua:

   fx_version 'cerulean'
   game 'gta5'
   
   files {
       'stream/**/*.ybn',
       'stream/**/*.ydr',
       'stream/**/*.ymap',
       'stream/**/*.ytyp',
   }
   
   data_file 'DLC_ITYP_REQUEST' 'stream/**/manifest.fymt'

   Also include _manifest.ymf if the pack author provides one.
2. Place all files (.ymap, .ytyp, .ydr, .ybn) inside stream/. Never mix an MLO and a YMAP that touch the same interior.
3. Declare the resource in server.cfg:

   ensure my_interior

4. Respect the ensure order. MLOs that depend on a custom IPL must load after it; place map resources high in the list, before gameplay scripts.
5. Detect conflicts. If two MLOs edit the same building, only one applies and the other flickers. Keep only one per interior or merge the ymap files in OpenIV.
6. Clear the server cache after every change: from txAdmin, Advanced → Server Actions → Clear server cache, then restart. On the client side, ask players to clear their cache if objects stay ghosted.

For a business ownership setup (stash, garage), also check that the MLO is compatible with your ESX/QBCore framework before declaring it.
