Add a short 1-second delay after terminating core processes on Linux, macOS, and in CoreAdminManager so ports and process resources have time to settle before the next step runs.
Renamed FileManager to FileUtils and updated all references accordingly. Moved SemanticVersion to the Models namespace. Replaced WindowsJob with WindowsJobService, relocating and updating the implementation. Updated usages in CoreManager and related classes to use the new service and utility names. These changes improve code organization and naming consistency.
