Subject: [PATCH] fix(process): treat non-ASCII letters as port continuations
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

\w is ASCII-only even with the u flag, so "port: 8080.β" was treated as
a sentence-ending port. Use Unicode letter and number classes for the
port boundary checks.
