This pull request simplifies the way the MachineGenerator executable target is defined in Package.swift. The previous approach used conditional compilation to define the target differently for Windows and other platforms. The new implementation unifies the target definition and uses the swiftSettings property to apply platform-specific compiler flags directly within the target declaration.

Target definition simplification:

• Removed the use of #if os(Windows) conditional compilation for defining the MachineGenerator target, consolidating both Windows and non-Windows logic into a single target declaration.
• Moved the swiftSettings for Windows (-parse-as-library) directly into the .executableTarget declaration using the .when(platforms: [.windows]) modifier, ensuring platform-specific flags are applied cleanly.

Codebase cleanup:

• Removed redundant or unnecessary swiftSettings from the GeneratorCommands target, streamlining the configuration.
