User-Agent claims Chrome 150.0.0.0

TLS cipher list matches no measured Chrome capture

The offered TLS cipher suites match no controlled capture of Chrome. Cipher lists are very stable per browser, so a different one is a real inconsistency — though a TLS-inspecting proxy re-originating the handshake is an honest cause, which holds this at medium.
