Handle non-interactive terminal environments gracefully

When MCC runs in non-interactive terminals (e.g. CI runners, IDE
embedded shells, piped input), several Console APIs throw exceptions
because there is no real console attached.

Changes:
- Program.cs: Wrap Console.KeyAvailable / Console.ReadKey in
  HandleFailure() with try-catch so MCC does not crash on startup
  failure in headless environments.
- Chunk.cs: Wrap Console.BufferWidth / BufferHeight in try-catch
  with fallback values (120x50) to prevent exceptions when rendering
  chunk maps without a console buffer.
- Map.cs: Same treatment for the map rendering path - use safe
  fallback values when Console.BufferWidth/Height are unavailable.
- ReplayHandler.cs: Replace Array.Reverse() (returns void in newer
  .NET) with .AsEnumerable().Reverse() to fix compilation with
  .NET 10 SDK where the void return breaks the fluent chain.
