The opening screen draws the name. v0.1.0-rc.3 renamed everything except the
wordmark, which still read SimpleDSH; the tagline named the old project too.
No behaviour changes.

Upgrading from SimpleDSH is described in
v0.1.0-rc.3:
existing workspaces keep their .dsh/, an existing key is still found, and
Sessions from an older binary continue without a cache break.
