Restore a Real Crafting Loop to Backpack Building (Ores, Ingots, Components)

The problem with backpack building:

The current backpack building system skips too many steps. Letting players mine raw materials and instantly weld blocks cheapens the experience, oversimplifies the game, and removes the engineering feel.

My suggestion and solution:

To restore depth, ores should be fully re-implemented across the board. The backpack should then follow a simple but meaningful crafting loop. After mining, the player selects a priority ore, and the backpack slowly refines it into ingots (but only for basic ores).

Using those ingots, players can queue (only basic parts) such as plates or tubes, etc, which the backpack slowly crafts before they can be used for welding.

This system also opens the door to meaningful upgrades. As players progress, backpack enhancements could improve refining speed, expand which ores can be processed, and allow slightly more advanced parts to be made on the fly while still remaining far slower and more limited than a proper refinery and assembler setup.

This brings back the true mine → refine → craft → build process that made SE1 great. It also keeps things straight forward for new players, and it makes construction feel like real engineering rather than just mining and instant assembly.

TL;DR: Reintroduce ores and add a simple backpack crafting loop where you slowly refine basic ores into ingots and craft basic parts before welding. This restores real engineering and keeps backpack building useful but balanced.
