Subject: [PATCH] fix(popup): seed lastKnownPeers in init() to prevent false
 join toasts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

init() called updatePeerList() directly but never set lastKnownPeers.
On the first PEER_UPDATE message (heartbeat, play/pause, any state
change), detectPeerChanges() saw lastKnownPeers=[] and treated ALL
peers including self as newly joined — triggering 'name joined the room'
toast on every action while the popup was open.
