PR: Module Renaming and Signal Refinement in Top-Level Game Module

This pull request implements structural improvements to the top-level game module, focusing on naming consistency and signal handling optimization.

Key Changes:

1. Module Renaming

   • Renamed module from 'top_game' to 'top_game_v' to better align with project naming conventions and improve module identification

2. Signal Declaration Updates

   • Modified input/output signal declarations to enhance clarity and maintainability
   • Refined port connections for improved signal flow and module interfacing

3. Internal Signal Routing

   • Updated internal signal routing to reflect the module rename
   • Revised instantiation references to ensure consistency across the module hierarchy

These changes maintain functional equivalence while improving code organization and readability. All dependent modules and testbenches should be updated accordingly to reference the new module name.
