Subject: [PATCH] fix(claw): detect the gateway's process title
 `openclaw-gateway`
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Upstream sets process.title="openclaw-gateway" in the gateway run loop, so
the real daemon has comm "openclaw-gatewa" (15-char truncation) and no
`node … openclaw` argv for the script probe to match. Add the exact comm
probe; substring matching stays out.
