`mac-approve` match the Allow sheet ("Allow remote debugging?" / "Allow") in non-English Chrome

Problem

mac-approve looks for the sheet titled Allow remote debugging? and a button described Allow. Chrome localizes both (Japanese: リモート デバッグを許可しますか？ / 許可する), so on any non-English UI it returns not-found and the handshake dies at 45 s.

Proposal

Identify the sheet structurally (the only sheet on Chrome's windows whose title mentions debugging, or the one containing the per-instance checkbox) and press the button by a label list — Allow, 許可する, … — overridable by env for languages not listed.

Alternatives considered

• Forcing Chrome to English (--lang) changes the operator's browser
• AXPress on the default button is unsafe (could be Cancel)
• driving the sheet by keyboard needs focus and steals it.
