Replace 495+ Console.WriteLine debug statements across handlers, dispatching, services, views, and window components with centralized DiagnosticLog service for proper logging infrastructure. Add new DiagnosticLog.cs service with Debug/Error methods to eliminate debug logging pollution in production code.
Incomplete functionality fixes:
- SkiaEditor: Wire up Completed event to fire on focus lost
- X11InputMethodService: Remove unused _commitCallback field
- SkiaWebView: Set _isProperlyReparented when reparenting succeeds,
use _lastMainX/_lastMainY to track main window position,
add _isEmbedded guard to prevent double embedding
Nullable reference fixes:
- Easing: Reorder BounceOut before BounceIn (static init order)
- GestureManager: Use local command variable instead of re-accessing
- SkiaShell: Handle null Title with ?? operator
- GLibNative: Use null! for closure pattern
- LinuxProgramHost: Default title if null
- SkiaWebView.LoadHtml: Add null/empty check for html
- SystemThemeService: Initialize Colors with default values
- DeviceDisplayService/AppInfoService: Use var for nullable env vars
- EmailService: Add null check for message parameter
Async fixes:
- SkiaImage: Use _ = for fire-and-forget async calls
- SystemTrayService: Convert async method without await to sync Task
Reduces warnings from 156 to 133 (remaining are P/Invoke structs
and obsolete MAUI API usage)
