fix(web): browser game UX pass — shake feedback, timer, stock count, HUD
- game.js fully rewritten: correct coordinate system (PAD baked into
PILE_ORIGIN), undo driven by undo_stack_len, flashIllegal shake with
--card-tx CSS variable, game timer, stock count HUD, URL seed persist,
foundation suit hints, auto-complete step loop
- game.html: adds hud-timer, hud-stock, win-time elements
- game.css: @keyframes illegal-shake, .slot-hint, overflow-x on main
- solitaire_wasm: adds undo_stack_len to GameSnapshot
