refactor: persist replay/save moves as KlondikeInstruction, not pile coords (#89)

Browse Source 
Pile-position types (Tableau, Foundation, KlondikePile, KlondikePileStack)
are runtime-only and have no serde upstream. Per Rhys's guidance, the
persistence layer now stores the moves (KlondikeInstruction) rather than
board coordinates, decoding back to runtime pile positions on demand.

Core / data:
- game_state: instruction_history() -> Vec<KlondikeInstruction>; add
  instruction_to_piles() and apply_instruction(); drop AnyInstruction.
- klondike_adapter: delete the entire Saved* serde mirror section
  (SavedTableau/Foundation/SkipCards/KlondikePile/TableauStack/
  KlondikePileStack/DstFoundation/DstTableau/SavedInstruction).
- replay: drop the bespoke ReplayMove serde mirror; Replay.moves is now
  Vec<KlondikeInstruction>; REPLAY_SCHEMA_VERSION 2 -> 3.
- storage: game_state save format v3 rejected (v4/v5 only).

Engine / wasm consumers:
- record via KlondikeInstruction (stock click = RotateStock).
- playback decodes each instruction to (from, to, count) against the
  live state via instruction_to_piles, then fires the canonical event;
  undecodable instructions are skipped with a warning, never panic.
- remove all use solitaire_data::ReplayMove and Saved* imports.

Workspace check, clippy -D warnings, and the full test suite all pass.
