Sync entire app to ~/.local/share/fluorine/bin/ for stable symlinks

The launcher now deploys the full application (not just Python) to the
central data directory on launch. Instance plugin symlinks always point
to this stable location instead of the tarball extraction dir, so they
survive moves/deletes of the original archive.
