Subject: [PATCH] fix: Waybar-Wrapper gibt immer Output aus
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fallback-JSON wenn corsairctl fehlschlägt oder Cache leer ist.
flock -w 5 statt -n damit der zweite Prozess wartet statt
sofort aufzugeben. Atomares mv statt direktem Schreiben in Cache.
