v1.20.2: CMS error handling improvements and auth fix

v1.20.2 is a patch release with CMS UX improvements and a small auth output fix.

CMS error handling improvements

  • Cleaner user errors — Invalid collection or item IDs now display a clean message and exit with code 1 instead of throwing a CLI error with a stack trace.
  • Structured API error bodies — When the Webflow API returns an error, the full structured error body from the response is now included in the output, not just the HTTP status code.
  • Next-steps hint after collections create — After successfully creating a collection, the CLI now prints a hint showing how to add fields to it: 
    $webflow cms collections create --site <siteId> --name "Blog Posts"
    $# ✔ Collection created: Blog Posts (id: abc123)
    $# → Add fields: webflow cms fields create --collection abc123 --name <name> --type <type>

Fix: duplicate “Credentials saved” output

Running webflow auth login no longer prints the “Credentials saved” line twice. Previously, both ensureAuthenticated and the auth login command handler logged the message independently.
