refactor: rename the project to usage-monitor

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.
