Update Kagi's Z AI Model from GLM 4.5 to Newly Released 4.6

Z AI released GLM-4.6 on September 30, 2025, bringing significant improvements over the current GLM-4.5 model available in Kagi Assistant. This feature request proposes adding GLM-4.6 as a new model option or upgrading from GLM-4.5 to 4.6.

GLM-4.6 delivers measurable enhancements that directly benefit Kagi users:

15-30% better token efficiency: Completes tasks with significantly fewer tokens, potentially reducing costs and improving response speed
Extended context window: Expanded from 128K to 200K tokens, enabling handling of larger codebases and more complex queries
Superior coding performance: Achieves near-parity with Claude Sonnet 4
Enhanced reasoning capabilities: Improved performance in agentic tasks and tool usage scenarios

Implementation approach:

Option A (Recommended): Replace GLM-4.5 with GLM-4.6 in the existing model lineup.
Option B: Add GLM-4.6 as a separate model choice alongside 4.5.

I feel it might be a good addition to Ki too.

+1 for this GLM-4.6 has big improvement, hope we can use it on Assistant soon.

The issue with GLM 4.6 is the providers that currently offer it are not ones we're integrated with. It couldn't even finish the 150 benchmark tasks in two attempts last week, either from openrouter or from deepinfra.

When we have a good provider setup with the model (normally we want two separate ones for a fallback) we're hosting it, we like the GLM series overall.
