The CLI's URL normalization was auto-prepending https:// to any URL
whose scheme wasn't in the allowlist (http, https, about, data, file).
This caused chrome-extension:// URLs to become
https://chrome-extension//... which fails with ERR_NAME_NOT_RESOLVED,
preventing navigation to extension pages (popup, side panel, options).
Add chrome-extension:// and chrome:// to the open command's scheme
allowlist, and update the record start/restart commands to preserve
any URL that already contains :// instead of only checking for http.
Fixes#409
