Refactor monitoring package: remove platform-specific files and consolidate OS detection and process counting logic

- Deleted os_windows.go and process_windows.go, replacing them with platform-agnostic implementations in unit directory.
- Removed Linux-specific process counting logic from process_linux.go and integrated it into unit.
- Consolidated uptime and OS name retrieval into unit files for better organization.
- Updated update mechanism to use global variables for current version and repository.
- Introduced command-line flags for configuration, including disabling auto-update and web SSH.
- Implemented WebSocket connection handling and terminal interaction for both Unix and Windows systems.
- Added basic info upload functionality to server package, enhancing monitoring capabilities.
