Fixes #83

When the LiveView connection drops and comes back within client_error_delay (3000ms by default), the show-error listener still reveals #client-error once the delay ends, after hide-error already ran. The notice then stays on screen while the page is connected, and phx-update="ignore" means no server render clears it. #server-error goes through the same listener.

The listener now keeps the pending setTimeout and hide-error clears it, so a reconnect inside the delay never shows the notice. A connection that stays down past the delay still shows it, and hide-error still hides it as before. The change touches only the two listeners in assets/js/live_toast/live_toast.ts, the rebuilt priv/static artifacts, one test in assets/test/live_toast.test.ts, and CHANGELOG.md.

Before / After

A single-file LiveView app with the default toast_group, a socket indicator polling liveSocket.isConnected(), and a button that runs liveSocket.disconnect(); setTimeout(() => liveSocket.connect(), 1500). Same steps in both recordings.
