- Move markdown and wiki-import tree into docs/; keep app shell at repo root
- Point docusaurus docs path to docs/; edit links to mleem97/gregWiki
- Sync and i18n scripts use gregWiki root and ../.wiki under gregFramework

+1. Install MelonLoader and run the game once.
+2. Copy `FrikaModdingFramework.dll` into `Data Center/Mods`.
+3. Add the mod that depends on FrikaMF.
+4. Check `MelonLoader/Latest.log`.

+- Wrong folder (`Mods` vs `RustMods`)
+- Missing first game start after MelonLoader install
+- Mixing incompatible game/framework versions
