Wipe Chrome session-restore state on boot (stop stale tab resurrection)

The persisted profile saves last-open tabs; on boot Chrome restored them,
resurrecting the removed Flow tab regardless of the launch URL. Delete
Sessions/ and Current/Last Tabs+Session so Chrome opens only the launch URL.
Cookies/logins are in separate files and untouched.
