Pushed some changes directly in c22a918.

• Scoped the accountless setup claims to a first clerk init run, since later runs keep an existing unclaimed app instead of replacing it unless you pass --fresh.
• Dropped "selected" from the env-file bullet — the accountless path re-detects the env file on its own rather than reusing the one init picks in context, so the two can diverge.
