Port sushi-go to use shared HandView & PileView components

[SorraTheOrc]

Port scenes in example-games/sushi-go that render or interact with hands/piles to use src/ui/HandView.ts and src/ui/PileView.ts.

Acceptance criteria:

• Scene(s) using hands/piles import and use HandView/PileView.
• Behaviour preserved (selection, draw/discard/recall, flip, reduced-motion).
• Tests updated or added; at least one headless smoke test passes for the migrated scene(s).
• Documentation updated (in-game README or inline comments).

Reference: CG-0MPDS1QWN004KKNJ (Gym migration)

Map

Implemented Enter key end-turn shortcut (configurable via Settings). Files changed:

• src/ui/SettingsStore.ts (new get/set for End Turn keybind)
• src/ui/SettingsPanel.ts (UI + capture flow for keybind)
• example-games/main-street/scenes/MainStreetLifecycleManager.ts (global key handler wiring)
• example-games/main-street/scenes/MainStreetRenderer.ts (hudOverlayContainer change to ensure consistent parenting in tests)
• tests/main-street/MainStreetScene.browser.test.ts (added positive + negative keyboard tests)
