feat: .deck → .contract.ts skeletal generation via TarotScript #2
Description
TarotScript already has:
- Recursive descent parser
- Manifest generation (property type inference from deck cards)
- DeckSlotContract validation framework
The Triad flow is: .deck (domain ontology) → .contract.ts (contract ontology) → generated code.
This issue tracks wiring TarotScript's spread engine to emit skeletal contract files from architectural spreads. Coordinate with Stackbilt-dev/tarotscript#138.
Depends on: contracts package stabilizing via FoodFiles validation (#1).
