v4.3.0 - Disable Fan Auto-Start & Hassfest Fix

What's New

Disable Fan Auto-Start (Issue #4)

When turning on the light or power switch on a hood device, the firmware automatically starts the fan. This new option prevents that behavior by sending an immediate fan-off command after power-on.

How to enable:

1. Go to Settings → Devices & Services → KKT Kolbe → Configure
2. Enable "Disable Fan Auto-Start"

Behavior:

• Light entity: When the hood is OFF and you turn on the light (e.g. via HomeKit/Siri), the integration powers on the hood and immediately suppresses the fan auto-start
• Power switch: When turning on the power switch (DP 1), the fan is immediately suppressed
• Fan entity: NOT affected - when you explicitly start the fan, no suppression occurs
• Edge case: If the hood is already ON, no fan suppression is sent (to avoid stopping a running fan)

Works with both enum-based (HERMES/STYLE) and numeric-based (SOLO HCM, ECCO HCM) fan control.
