Deconstruct VncThumbnailViewer 1.4.2 and add self-contained build

The shipped VncThumbnailViewerWin1.4.2.exe is a native launcher stub with a Java JAR appended. This commit adds: - src/: full Java source recovered from the bundled .class files (CFR), plus src/summary.txt with decompiler caveats - ANALYSIS.md: architecture, data flow, hosts-file format, and security notes - build-app-image.ps1: reproducible jpackage build that repackages the original classes and bundles a slim jlinked runtime (java.base + java.desktop) into a self-contained native app-image (no Java required on the target) The 74 MB app-image is shipped as a release asset rather than tracked.
