Modularization racial/unique/advanced tech

Basically it's weapon platforms but they can install other components such as new resource extractors specific to them as well.

Start by clarifying the intended modularization of weapon platforms and how installable components should work, including resource extractors specific to each platform. Define the supported component types, compatibility rules, and expected in-game behavior before identifying implementation entry points. Done should mean the requirements are precise enough to implement and verify.
