feat(status): quiet mode mutes the Claude and opencode sounds

A new registry mode, status.quiet, with a row on the status page. Both tools
will play their sounds through notify-sound, which asks statusctl and plays
nothing while quiet is on, so their popups stay and only the sound goes.
Presentation sets quiet and restores it afterwards, like dnd and nolock: a
sound during a call or a game is what quiet is for.

notify-sound ignores any argument it has no sound for, because the opencode
notifier runs its command on every event, session_started and user_message
included.
