Subject: [PATCH] fix: use unique workspace per command execution to prevent
 concurrent conflicts (#1114)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commands for the same site shared a workspace key based only on site name,
causing concurrent commands to interfere — one command closing the automation
window would detach the other mid-execution.

Append a random UUID to the workspace key so each command gets its own
browser session, preventing the 'Detached while handling command' error.
