Perfect Sync v0.1.6

IMPORTANT: v0.1.6 performs a one-time reset of existing profiles,
personal mod selections, configured game sources, immutable bases, and
private workspaces, then opens first-time setup. Select a fresh, untouched
Among Us installation; verify or reinstall the game first if needed. The
chosen large-data storage location and GitHub credential are kept.

Experimental release, nothing official or stable yet. Expect rough edges
and breaking changes. See CHANGELOG.md for details and known limitations.
