fix: preserve prefix only for native OpenRouter models (single-segment)

Browse source 
Native models like openrouter/auto, openrouter/free have no extra '/'
after the prefix. Provider-routed models like openrouter/anthropic/claude
have extra segments and need prefix stripping.

Condition: only early-return when model after 'openrouter/' has no '/'.
