Public help center and release notes

What changed for people using Bellwether

• The help center is public. Anyone can read every help article and search them without signing in; the pages open in a visitor frame with a sign-in link instead of the console navigation. Asking Consult about an article still needs an account.
• Release notes have a home. A public "What's new" page lists each release in plain words, with an RSS feed for people who want updates in a reader; signed-in users get a "What's new" entry in the account menu with a quiet dot until they have seen the latest note.
• Ask Consult about a help article now attaches the article as a small context pill instead of pasting a machine-written sentence into your message, starts a fresh conversation, and Consult reads the article itself so the answer comes faster.
