fix: CI workflow fixes and AOT-safe JSON serialization

- Android: install full MAUI workload (not just maui-android) for
  multi-target csproj dependency resolution
- PyPI: override TargetFrameworks to net8.0 so MAUI workloads are not
  needed on ubuntu CI runner
- pub.dev: remove iOS simulator xcframework slice before publishing to
  stay under 100 MB package size limit
- Replace reflection-based JsonSerializer calls with source-generated
  JsonSerializerContext to eliminate IL2026 trimming warnings
