Alloycraft expansion: recipes, challenges, and recipe scrolls

Alloycraft has been completely expanded. The discipline now has weapon options for every build type starting at level 1 — a dagger, ranged launcher, heavy bludgeon, catalyst rod, and tome offhand are all craftable with nothing but scrap metal and crystal shards. No more grinding to discipline level 6 just to craft something your class can actually use.

Added a Crafting Challenges system. Some of the most powerful Alloycraft gear is now locked behind combat milestones: kill 250 monsters to unlock epic boots, complete 3 quests for an epic ring, kill 3 unique bosses for the Fracture Blade, discover 4 zones for the Signal Choker, reach 500 kills for the Void Chassis, and 1000 kills for the Etched War Plate. Each locked recipe shows a live progress counter (e.g. "Kill 250 monsters — 127/250") so you always know exactly how far you are. Challenges unlock automatically when the threshold is crossed.

Introduced recipe scrolls — rare data-slate drops from elite monsters and minibosses that permanently unlock endgame fabrication recipes unavailable any other way. Four scroll recipes to find: Voidhunter Blades, Void Catalyst, Apex Resonance Cannon, and the Architect's Compendium. A Scrolls tab appears in your inventory when you carry one. Tap "Learn" to consume the scroll and add the recipe permanently.

The Fabrication screen's recipe list now sorts challenge-locked recipes to the bottom, below level-locked and material-locked entries. Locked cards show the padlock icon, hint text, and progress counter in both collapsed and expanded state.
