v0.1.0 — Phase 1: Go Backend + SQLite + Seed Data

- Wails project setup (Go + React-TS)
- SQLite schema (allergens, additives, products, week_plans, plan_entries, special_days)
- 14 EU allergens (LMIV 1169/2011)
- 24 German food additives
- 99 products imported from Excel with allergen/additive mappings
- Full Wails bindings (CRUD for products, week plans, entries, special days)
- OTA updater stub (version check against HTTPS endpoint)
- Pure Go SQLite (no CGO) for easy Windows cross-compilation
