Enhance Tailscale Receiver with new features and improvements for version 2.3.0.

- Introduced optional systemd timer mode for power-efficient operation, allowing the service to run every 30 seconds.
- Added Nautilus (GNOME) integration for right-click context menu support, enabling file sending directly from the file manager.
- Implemented comprehensive polling and performance settings, including health checks, file integrity verification, and virus scanning options.
- Enhanced README documentation to reflect new features, including detailed configuration options and usage examples.
- Improved error handling and logging throughout the scripts for better user feedback and reliability.
- Updated Makefile to support building Debian and RPM packages, streamlining the installation process for users.
