Subject: [PATCH] fix(feishu): correct inverted dedup condition
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

check() returns false on first call (new key) and true on subsequent
calls (duplicate). The previous `!check()` guard was inverted —
dropping every first delivery and passing all duplicates.

Remove the negation so the guard correctly drops duplicates.
