Qiaochu HuandClaude 0de67c537a fix(extension): roll back CDP attach when a domain enable fails ...

If `chrome.debugger.attach` succeeds but a subsequent CDP domain enable
rejects — most notably `Page.enable`, when the tab navigates to a
chrome:// URL or the Web Store in the gap between the two calls — the
driver left the tab in an unrecoverable state. `attachedTabs` never
recorded the tabId, so the next `ensureAttached` re-attached and failed
permanently with "Another debugger is already attached" until the
extension was reloaded.

Detach the debuggee directly in the failure path (the public `detach()`
is a no-op here because the id is not cached yet) so the next attempt
starts from a clean slate. Adds a regression test that fails on the
previous code, where the rollback never ran and `detach` was never
called.
