Three packaging defects rolled into one fix:
- The custom DalamudPackager.targets override forced HandleImages and
ImagesPath through the legacy code path. SDK 15 handles images by
default and the override produced an output manifest with neither
IconUrl nor ImageUrls populated. Removed.
- The csproj only included images/icon.png explicitly via
<None Include>, so chatWindow.png and withSimpleTweaks.png never
reached the build output and never made it into the release ZIP
either. Switched to a glob include.
- HellionChat.yaml carried no icon_url / image_urls, so even after
the SDK started writing the manifest correctly, both fields stayed
unset. Added them pointing at the public raw.githubusercontent
URLs that already work for the repo.json IconUrl.
Net effect on a fresh release: Dalamud picks up the icon next to the
DLL on dev installs, the plugin-installer card shows the proper
HellionChat logo for users coming through the custom repo, and the
two screenshot images are listed alongside the description so the
plugin installer carousel works the way other Dalamud plugins look.
