## Summary
- Removes the invalid `/debug` flag from signtool parameters in
`windowsSign.ts`
- The `/debug` flag is not a supported signtool option and was causing
Windows builds to fail with `SignTool Error: Invalid option: /debug`

## Test plan
- [ ] Verify Windows release build succeeds by running the Release
workflow

> [!NOTE]
> **Low Risk**
> Low risk: a one-line change to Windows code-signing flags that only
affects signing invocation and should reduce build failures.
> 
> **Overview**
> Removes the unsupported `/debug` option from `windowsSign.ts`
`signWithParams`, leaving only the verbose (`/v`) and Azure signing
library/metadata parameters. This aims to prevent `signtool` from
failing Windows builds due to an invalid flag.
