- solitaire_wasm: add SolitaireGame::serialize() and from_saved() so JS
can round-trip the full GameState through localStorage as JSON
- game.js: save {gameState, elapsedSecs, drawThree} to localStorage
(key: fs_game_save) on every render(); clear the save on win
- game.js: on bootstrap, check for a saved game and show a resume
dialog if one exists; Resume restores state + timer, New Game discards
the save and starts fresh with a random seed
- game.html: add #resume-overlay markup (same pattern as win-overlay)
- game.css: add styles for the resume dialog and its secondary button
localStorage failures (private-browsing quota) are silently ignored so
they never block gameplay.
