Unexpected value of suite.fullUrl on Windows

[generalov]

Output of gemini --version:
5.6.2

I've noted that html-reporter plugin produces data.json which contains invalid value in metaInfo.url property on Windows:

metaInfo: {
  url: "\\\\user\\profile.html\\",
}

Expected:

metaInfo: {
  url: "/user/profile.html",
}

The plugin uses value from suite.fullUrl to put in the report. Root cause of the issue is in

gemini/lib/runner/browser-runner/index.js

Lines 47 to 52 in 7c709d7

	_mkFullUrl(suiteUrl) {
	const rootUrl = this._config.rootUrl;
	const urlObj = url.parse(rootUrl + '/' + suiteUrl);
	return path.resolve(path.normalize(urlObj.path));
	}

The _mkFullUrl() function calls Node.js path module. But the module is intended to deal with filesystem paths rather URLs. It could return unexpected results on *nix systems too.

Perhaps url-join package or something like that could be used to concatenate URLs correctly.
