feat: Windows64 local multiplayer support (#13)

- Skip QuadrantSignin (profile selector) on Windows64 in both LoadMenu
  and CreateWorldMenu, proceeding directly to local play since Xbox Live
  stubs always return true for IsSignedInLive()
- Fix IsLocalMultiplayerAvailable() to not require IsHiDef() on Windows64
- Allow pad-connected players to join without a profile sign-in check
- Fix ghost RemotePlayer creation by scanning all local player slots and
  matching on server-assigned player index rather than controller slot,
  fixing P3/P4 ghost entities when joining out of controller order
- Give each player a unique name (Player 1-4) based on controller index
  instead of a single shared stub name
- Use raw XInput (XInputGetState) for secondary controller join detection,
  bypassing the 4J toggle system which consumes all button presses before
  game logic runs; uses a 120-frame latch for a reliable detection window
- Add .gitignore for Visual Studio build artifacts and output directories
