0.51.0

Added

• zm <profile> session start --json --answer-stdin signs in from WireCat Desktop (cli-core 0.443.0). The Zoom
  page to approve is an open_url line on stderr instead of the plain one, and the fallback paste of the address the
  browser ended on is a needs line answered with one line on stdin; when the browser's callback comes first, the
  question is withdrawn. Without --answer-stdin nothing changes.
• zm now builds on cli-core 0.443.0 and cli-base 0.59.0, the range cli-core 0.443.0 needs.
• contacts list and contacts show read your Zoom contacts live from Zoom: company colleagues and external
  contacts, with name and email, and phone numbers in show. name:, email: and type:company|external narrow
  the list. Each contact is the shared contact type, keyed by Zoom's member id. They need the
  team_chat:read:list_contacts and team_chat:read:contact scopes and a new session start.
• The Zoom response checks are generated from Zoom's published Chat API description (spec/zoom/, pnpm zoom:generate).
• zoom search searches your Zoom workspace live through Zoom's own search: chat messages, chats, Canvas docs, meetings and the rest of what your account holds, chosen with --only. It needs the agentic_search:read:search scope; Zoom's ask answers are not offered.
