v0.17.0

A ready-made setup for Gateweave Mail, and applying a setup now merges into a repository's .vscode/mcp.json instead of
replacing it. There is no migration in this release.

Added

• A ready-made Gateweave Mail setup. It adds Mail's skill and MCP server to a repository, for Claude Code, Codex,
  Gemini CLI, Cursor and GitHub Copilot, so their agents can read sign-up codes, wait for mail and send it. Adding it
  asks for your Mail's MCP address. The agent's key is read from GATEWEAVE_MAIL_KEY and never written to the
  repository. The setup has no instructions, so it leaves a repository's AGENTS.md and CLAUDE.md alone.
  (#202)
• A setup can ask for an MCP server's address. For a server that every install runs at its own address, an
  askUrl in setup.json makes the Setups page ask for it when the setup is added. The address is checked as one
  typed on the MCP page is. The CLI takes it as --url <server>=<url> from its next release.

Fixed

• Applying a setup no longer replaces .vscode/mcp.json. It replaced the whole file, so the repository's other
  servers and its inputs were lost. Only the setup's own servers are merged in now, as in the other MCP files.

If you run your own

• Nothing to do for this release.
• CI's browser tests install Chromium alone when Ubuntu's package mirror can't be reached.
