refactor(core): unify Suit/Rank with card_game upstream types

Replace the parallel solitaire_core::Suit and solitaire_core::Rank
definitions with pub-use re-exports from card_game. card_game upstream
gained serde, is_black(), and value() to make this clean.

- card.rs: remove Suit/Rank enums and impls; add pub use card_game::{Suit,Rank}
- klondike_adapter.rs: remove From<card_game::Suit/Rank> bridges (now same type)
- Simplify card_from_kl: .into() calls become direct assignment
- Cargo.toml: switch to git deps (serde feature), Cargo.lock updated

All 62 solitaire_core tests pass; clippy clean.
