feat: erste Fassung der ninstrip-Integration fuer Home Assistant
Auf dem Geruest von ha-ninlight aufgebaut und bewusst parallel gehalten: gleiche Fehlerklassen in api.py, gleicher Coordinator mit Sperre und Fehlertoleranz, gleicher Einrichtungsablauf samt Zeroconf und Reauth. Eigenes Repo statt Erweiterung von ha-ninlight: die Geraete melden sich unter verschiedenen mDNS-Diensten, das Datenmodell unterscheidet sich deutlich (Segmente und Szenen gegen ein einzelnes Licht), und ha-ninlight laeuft produktiv mit vier Lampen - Verzweigungen dort haetten beide Produkte gefaehrdet. Entitaeten: light (Hauptschalter und Helligkeit), select (Szene), button (Neustart), vier Diagnosesensoren. In ha-dev eingebunden und am echten Geraet geprueft: Aus- und Einschalten, Helligkeit 40 Prozent, Szenenwechsel auf Regenbogen - das Geraet meldet jeweils genau das zurueck.
