Browser-based Google and GitHub sign-in entry points, plus the related TOTP continuation flow. The auth controller currently exposes these browser entry points:
ProviderStartCallback
GoogleGET /auth/googleGET /auth/google/callback
GitHubGET /auth/githubGET /auth/github/callback
If a user has TOTP enabled, complete the sign-in flow with:
  • POST /auth/totp/verify
Workspace-scoped Google OAuth connections are documented separately under the workspace overview because they live under /workspaces/{workspaceId}/oauth-connections/google.
