Remove the (from, to, count) tuple as an internal move-passing wrapper.
Game logic now stays in KlondikeInstruction space end to end:
- Add GameState::apply_instruction, the native apply path. move_cards
becomes a thin pile-coordinate adapter that converts to an instruction
and delegates, so move bookkeeping (validation, score/recycle history,
undo snapshot) lives in one place instead of being duplicated.
- next_auto_complete_move matches DstFoundation directly instead of
projecting every candidate to pile coordinates.
- proptests and the storage round-trip test apply instructions directly
rather than round-tripping instruction -> tuple -> move_cards.
The single instruction -> pile decode is renamed instruction_to_highlight
-> instruction_to_piles and kept in core: decoding a tableau run length
needs upstream pile-stack types core does not re-export, so relocating it
would duplicate the logic across engine and wasm. The two rendering edges
(engine hint highlight, wasm debug move list) call this one decoder; the
engine's hint_piles is a thin delegation to it.
Also includes the CardEntityIndex render-side index and a SelectionPlugin
init_resource fix so update_selection_highlight no longer panics in test
harnesses that omit CardPlugin.
