Release v0.4.0-alpha

Added

• URI-based screenshot detection in ScreenshotContentObserver (query by content URI ID instead of scanning latest)
• Deduplication with synchronized processedUris/pendingUris sets to prevent duplicate processing
• Retry logic with queryByIdWithRetry (3 attempts with 500ms delay) to handle MediaStore index race
• clearProcessedUris() lifecycle hook called after cleanup work completes
• goAsync()/pendingResult.finish() pattern in BootReceiver and NotificationActionReceiver for proper BroadcastReceiver lifecycle
• contentObserver reference on SsJanitorApp to enable cleanup worker to reset dedup state
• notificationManager lifecycle management in ScreenshotDetectionService (dismiss on destroy)
• REQUEST_IGNORE_BATTERY_OPTIMIZATIONS permission declaration for battery optimization opt-out
• Battery optimization check with re-evaluation on lifecycle resume
• AutoStartUtil — OEM-specific auto-start settings intents (Xiaomi, Huawei, OPPO, vivo, OnePlus, Samsung)
• EmptyStateView subtitle parameter for multi-line empty state messages

Changed

• Switched SsJanitorApp database/repository/settings from lateinit to by lazy for thread-safe initialization
• Refactored ScreenshotDetectionService.onCreate() to start foreground in onCreate (moved out of helper method)
• Simplified ScreenshotCleanupWorker — removed dead autoDelete = true branch; always deletes archived screenshots
• Shared single CoroutineScope(Dispatchers.IO) in ScreenshotContentObserver instead of creating per-screenshot scopes
• BootReceiver exported attribute set to true for reliable BOOT_COMPLETED delivery on modern Android
• Permission warning card now includes "No Kill" and "Auto Start" action buttons
• Empty state message split into separate lines with kept count subtitle
• Animated stats grid entrance and extracted auto-archive badge
• Tracked file size for screenshots with freed-up bytes display

Removed

• All Log.d/Log.e/Log.w statements across the codebase (production code cleanup)
• ScreenshotDetector stale-run guard log messages

Fixed

• ContentUris.parseId() crash path — wrapped in try/catch for NumberFormatException
• queryByIdWithRetry — fixed to 3 total attempts (was 4 due to fallthrough)
• BootReceiver — missing goAsync() which could cause ANR on boot
• NotificationActionReceiver — missing goAsync() which could cause ANR
