Linux-related stdio fixes and update version (#22)

- Modified `GetCommand` to return OS-specific commands and changed return type to `string?`.
- Improved `InitializeCommand` for better command initialization and logging.
- Cleaned up using directives in `Log.cs` and `SseClientTransport.cs`.
- Updated `CreateNoWindow` property in `StdioClientTransport` to be OS-dependent.
- Bumped version number in `mcpdotnet.csproj` to 1.0.1.1.
