islands: extract in-game names (Landmark -> Toponym), incl. Wunderinsel = Strudel

Definitive island prefab -> in-game name link: each island_* prefab has a child Landmark
GameObject (LandmarkBehaviour.name) = the Toponym key, localized via i2 Toponyms/<name>.
New bundle/extract_island_names.py -> extracted/island_names.json.

Key results: Demo_Wunderinsel=Strudel, Demo_Marktinsel=Segen, Gartenfreude=Insel St. Clemens,
DeusExMashineSmall=Rauchwolke, and island_Factorio = Sprengstofffabrik (the explosives
factory). The LittleFactory/LittleFactoryArmory prefabs are the Forts.

Updates docs/PRODUCTION_LINES.md with in-game names and corrects the earlier Sprengstofffabrik
note (it IS the explosives factory -> Factorio, not the Armory islands). Supersedes the
name-guesses (e.g. DeusExMashine is Rauchwolke, not Maschineninsel).
