Root cause confirmed: routed target models were rebuilding the model without preserving thinkingLevelMap metadata.
Fixed the router model builder to keep the target model’s reasoning mapping metadata when constructing the routed target model.
Added a focused regression test covering mapped reasoning levels (minimal -> low) on routed provider models.
Ran the focused router e2e suite; the reasoning-map regression passes.
One unrelated stall-status test in the same file still fails and is outside the scope of this issue-specific fix.

Fixes #9
