Feature Request: Support GLM 4.6 Image Recognition

[cckenaaa]

According to the official GLM pricing and feature page, GLM 4.6 supports image and video understanding under the “Pro” and “Max” plans. However, it seems that Kilo Code currently does not support image recognition capabilities when using GLM 4.6.

Kilo Code should allow users to use GLM 4.6 for image recognition (e.g., analyzing uploaded or pasted images), consistent with the official GLM capabilities.
