v0.1.7

Wording release, from scoring the prompt-1 agent eval runs against 0.1.6. The
templates and the suite are unchanged.

Changed

• SKILL.md quick start, step 1, and references/adaptation.md: no session is
  signed out, in every environment. A request without a session or a tenant is
  a 401 or a redirect to sign-in, never a development user, a sandbox tenant
  or a first-tenant default.
• SKILL.md framing paragraph tightened to stay within the line budget;
  references/provenance.md records the addition.
