CrossWatch v0.9.19

Just a small cleanup release.
Icons now load locally for better privacy and the exporter provider selector no longer shows a duplicate dropdown.

We are getting close to the v1.0.0 production thus stable release. From that point onward, production and development releases will be handled separately, so stable users can stay on reliable builds while development changes can continue without disturbing the production version.

🔧 Fixes & Improvements

• Improved: Material Symbols icons are now loaded locally instead of from Google Fonts, improving privacy and compatibility with restricted networks.
• Fixed: The exporter now shows only the intended icon-based provider selector instead of rendering a duplicate dropdown.
• Changed: Updated the version to v0.9.19
