feat: Integrate Kilo gateway

[micuintus]

What does this PR do?

Integrate the Kilo Gateway package from https://github.com/Kilo-Org/kilo/tree/dev/packages/kilo-gateway into openCode.

Why do that? Allow using the free GLM 5 tier.

Can we do that?

see #5709

Do we want that?

--> I do, but eventually you have to decide

My approach

1. Pull in Kilo as a depency
2. Have GLM-5 help me integrate it

How did you verify your code works?

Use it with my changes :)

Closes #13767
