Windows CI failed because smoke.ps1 nested bare 'powershell' (often 5.1)
to run verify-routing-coherence.ps1. PS5.1 mis-parsed UTF-8 Chinese source
without BOM, so nested verify exited 1 while the standalone pwsh verify step passed.
- Resolve SmokeHostExe from current process (pwsh on GHA windows-latest)
- Rewrite nested invocations to use $SmokeHostExe
- Write UTF-8 BOM on smoke.ps1 and verify-routing-coherence.ps1 for PS5.1 safety
