refactor(engine,wasm,data): route all klondike/card_game imports through solitaire_core

All downstream crates now import Foundation, KlondikePile, Tableau,
Klondike, Session, Suit, Rank exclusively from solitaire_core.
solitaire_core is the single version-pin point for the upstream crates.

- solitaire_engine: 19 files updated, klondike direct dep removed
- solitaire_wasm: use statement updated, klondike direct dep removed
- solitaire_data: unused klondike dep removed
- Cargo.lock: klondike no longer a direct dep of engine/wasm/data
- Full workspace clippy clean, all tests pass
