0.3.0

Added

• thinger dashboard dev [url]: develop a dashboard app on its own dev
  server (ng serve, Vite…) against a real server: a link with a temporary
  token opens the local app as a standalone page whose SDK calls the server
  directly.
• thinger dashboard publish [dir]: upload the build to a public storage
  and point dashboards at it (--to, repeatable; --prune, --bump,
  --preview, --no-point). Both read their settings from thinger.json.
• thinger dashboard init <dir>: a new dashboard app from a template of
  @thinger-io/dashboard-sdk (React or Angular, TypeScript), with its
  thinger.json and an AGENTS.md; --ci adds a GitHub workflow.
• Publish and dev warn when the app's SDK needs a newer server, a newer SDK
  is on npm, or a page loads the deprecated script build.
• MCP tools thinger_dashboard_init and thinger_dashboard_dev (25
  tools): the same for agents, which open the dev link with their browser
  tools.
• THINGER_TOKEN (an access token) and THINGER_SERVER replace the saved
  profile in every command and the MCP server (CI), unless --profile or
  THINGER_PROFILE names one; thinger login warns while THINGER_TOKEN
  is set.

Changed

• Requires @thinger-io/cli-core 0.4.0.
• The guides for agents (thinger_doc_read: concepts, product code, server
  administration, the dashboard SDK reference and types) ship with the CLI
  and the SDK package instead of coming from the server, which stops
  serving /sdk/. Same ids; what needs a newer server says "since Thinger
  X".
• Preview links no longer come with a layout check link: the server
  retires /sdk/preview.html.
