v1.7.0

• Removed Gemini CLI support; Gemini CLI has been retired in favor of
  Antigravity.
• Removed Cursor support.
• Fixed the MCP servers failing to start on a fresh install ("Couldn't resolve
  the package 'dart_mcp'"). The Claude Code and Copilot manifests now launch
  servers with dart pub -C <plugin-root> run, since dart run <abs-path>
  only resolves dependencies for the current directory's package. A new test
  launches each server from a fresh copy to catch regressions.
  As a side effect, server startup is faster (dart pub run caches a compiled
  snapshot): roughly 0.3–0.7s instead of 1–5s.
