fix(self-managed-stack): bump llm-request-router pin to 1.6.6

[Max-NV]

Why

The self-managed stack pinned llm-request-router chart 1.6.3 (stargate image 0.3.0). The 0.3.2 image adds a --backend-connectivity gate; chart 1.6.5 took the 0.3.2 image without passing the flag and crash-loops the router. Chart 1.6.6 (#248) passes --backend-connectivity=reverse.

What changed

Bump the llm-request-router pin 1.6.3 -> 1.6.6 in the self-managed core helmfile, picking up the stargate 0.3.2 image and the crashloop fix together. Keeps main-line (0.7.0) from regressing into the same crashloop when it moves onto the 0.3.2 image.
