Initial commit: MTG personal library catalog (Tauri v2 + React/TS)

Full working app with:
- Rust core (mtgc-core): Scryfall ingester, nucleo fuzzy search, SQLite two-DB
  architecture (reference.db + library.db via ATTACH), criteria filters, deck ops
- Tauri v2 shell exposing the core as typed IPC commands
- React/TS frontend: card entry, library browser, deck editor
- Features: fuzzy card search, color/CMC/type/commander-identity filters,
  tile/list view toggle, hover card previews, deck format + commander support,
  per-card location field, grouping by type/subtype/CMC/color, localStorage
  persistence for active tab/deck/grouping, Discord-inspired dark UI (#C8553D accent)
