fix: resolve TypeScript inference issue in client-path.ts

Add explicit type annotation for webssh2Client module to prevent
TypeScript/ESLint from incorrectly inferring it as 'error' type.

This fixes CI error:
- Unsafe return of a value of type error
- Unsafe call of an 'error' type typed value
- Unsafe member access .getPublicPath on an 'error' typed value

The explicit type cast helps TypeScript understand the module structure
when type inference fails in certain environments.
