0.4.0

The crafting update. 🔨

• Crafting page — craft value-add margins for 635 recipes, computed live at sweep time: sale price × yield − ingredient cost at the cheapest current listings, crystals included. Ranked by margin × daily sales and filtered by default to crafts that use what you can farm right now (recipes with vendor-only ingredients are excluded rather than mis-costed).
• Market drill-down — click any row on the Sweep page: live listing depth, recent sales, days-of-stock, and an hour-of-day posting-window histogram in your local time.
• Sparkline backfill — fresh installs pull one round of Universalis sale history per world (quantity-weighted daily averages), so the trend lines have shape from the first minute.

Note: the portable exe is unsigned — Windows SmartScreen will warn on first run (More info → Run anyway).
