browser.computer_use.endpoint cannot be empty

Error message

browser.computer_use.endpoint cannot be empty

What it means

computer_use_endpoint_url rejects an empty (after trim) browser.computer_use.endpoint. The computer-use backend cannot be reached without an endpoint URL, so backend resolution fails early with a config-fix message rather than a network error later.
