Rename the crate, binary, product name, identifier, settings folder, log
file, autostart entry, user agent, updater endpoint and release assets.
Legacy Win32 clients still update: they fall back to the first .exe asset,
and the legacy rollback workflow reads the package name from the ref it
builds. Upgraded installs start with default settings.
The bundler has no icon fallback, so an empty list breaks the AppImage
step and ships a deb without hicolor icons. Put icon.png first so it stays
the default window icon on Linux and macOS, and bundle the deb in the
Linux CI row to catch a broken list before release.
Windows and Ubuntu 22.04 run fmt, clippy, tests, lint, the JS tests and
a no-bundle release build. The Windows row checks the exe version
resource and uploads the exe as a 7-day artifact. macOS runs cargo check
as the compile gate.
