Refine MediaProjection permission and screenshot initiation logic.
This commit implements the following changes: 1. Introduces an `isProcessingExplicitScreenshotRequest` flag in MainActivity to differentiate between permission requests originating from app startup versus those from explicit screenshot commands. 2. Modifies `MainActivity.screenshotRequestHandler` to set this flag when an explicit screenshot request requires permission. 3. Modifies `MainActivity.mediaProjectionLauncher` to only start `ScreenCaptureService` if the permission was granted as a result of an explicit request (i.e., the flag is true). The flag is reset afterwards. 4. Restores the call to `requestMediaProjectionPermission()` in `MainActivity.onCreate()` to ensure permission is prompted at startup if not already granted. Due to change #3, this no longer auto-starts the capture service. 5. Confirmed that the `takeScreenshot()` call within `ScreenCaptureService.startCapture()` is necessary to fulfill the explicit screenshot request that leads to the service starting. This is no longer an "unwanted automatic" screenshot but part of the explicit flow. This addresses your feedback to: - Ensure permission is requested at app startup. - Prevent this startup permission request from automatically taking a screenshot. - Ensure explicit screenshot requests function correctly. - Remove any other unintended automatic screenshots.
