Previously the engine silently restored any saved in-progress game
from `game_state.json` on startup. Players who launched expecting a
fresh deal got dropped back into a half-played game with no signal
that a save had been picked up; players who wanted to continue had
no clear acknowledgement either way.
Now: when launching with a saved game that has at least one move
and isn't already won, the engine holds the saved state in a new
`PendingRestoredGame` resource and seeds `GameStateResource` with
a fresh deal. Once the splash overlay finishes, a modal appears:
Welcome back
You have an in-progress game. Continue where you left off, or
start a new one?
[New game] [Continue]
- Continue (Enter / C / click) — swaps the saved game into
`GameStateResource` and fires `StateChangedEvent`. Card sprites
resync to the restored layout.
- New game (N / click) — drops the saved state, fires
`NewGameRequestEvent { confirmed: true }`. The existing
`handle_new_game` flow then deletes `game_state.json` and deals.
Save files with `move_count == 0` (a fresh deal that was never
played) skip the prompt and load directly — there's nothing
meaningful to "continue" there. Won games skip too (the existing
flow already deletes their save file on win).
The spawn system gates on `SplashRoot` being absent so the modal
doesn't pop up over the brand splash on first launch.
