| 9 | * Handles plugin uninstallation and cleanup of WP Staging data |
| 10 | * |
| 11 | * This class manages the complete uninstallation process including: |
| 12 | * - Detecting single site vs multisite/network uninstall scenarios |
| 13 | * - Distinguishing between Basic and Pro version uninstallation |
| 14 | * - Preserving data when both versions are installed |
| 15 | * - Cleaning up options, transients, and cron events |
| 16 | * - Removing plugin directories (except those containing backups) |
| 17 | * - Respecting user's "Remove Data on Uninstall" setting |
| 18 | * |
| 19 | * The class runs in standalone context without the plugin's autoloader, |
| 20 | * so it must be self-contained with no external dependencies. |
| 21 | * |
| 22 | * Note: Avoids using class constants to prevent loading the whole plugin. |
