color_mode property missing — HomeAssistantError on every poll

[DaveBulldozer]

On v2026.4.2 of Home Assistant, the light platform requires every light entity to implement both supported_color_modes and color_mode. The integration currently only implements supported_color_modes, which causes HA to throw a HomeAssistantError on every polling interval (~every 10 seconds), flooding the logs.

Error
homeassistant.exceptions.HomeAssistantError: light.bulldozers_light_bars (<class 'custom_components.govee.light.GoveeLightEntity'>) does not report a color mode

Full traceback originates in update_coordinator.py → async_update_listeners → async_write_ha_state → __async_calculate_state → state_attributes in homeassistant/components/light/init.py.
Root Cause
GoveeLightEntity in light.py implements supported_color_modes (line ~160) but is missing the color_mode property that HA now requires to return the currently active mode.

Fix
Add the following property to GoveeLightEntity directly after supported_color_modes:
python

@property
def color_mode(self) -> ColorMode:
    """Get current color mode."""
    supported = self.supported_color_modes
    if ColorMode.HS in supported:
        return ColorMode.HS
    if ColorMode.COLOR_TEMP in supported:
        return ColorMode.COLOR_TEMP
    if ColorMode.BRIGHTNESS in supported:
        return ColorMode.BRIGHTNESS
    return ColorMode.ONOFF

This derives the current mode from the supported modes, which is consistent with how the rest of the entity is structured. A PR with this fix is attached.
Environment

Home Assistant (Docker, latest)
Ubuntu 24.04
