v0.2.2: fixes the running window/taskbar showing the generic Java icon

instead of Huck's own (Window's icon parameter wasn't set). Carries
forward v0.2.1's NoClassDefFoundError fix unchanged.

v0.2.1: fixes the packaged .msi crashing on connect() with

NoClassDefFoundError: java/net/http/HttpClient (jpackage's trimmed JDK
runtime was missing the java.net.http module; includeAllModules = true
bundles the full JDK instead). Everything else from v0.2.0 carries
forward unchanged.

v0.2.0: selection, delete, save/open/download, the right-click context

menu, a real Windows app icon, and a working release-publishing CI
pipeline -- all confirmed working against zouk on real hardware.
