Subject: [PATCH] fix: add timeout handling to registryValidation to prevent
 CLI hang

When --registry-url points to an unreachable host, the CLI would hang
indefinitely due to fetch() having no timeout. This fix:

- Adds AbortController with a 5-second timeout
- Uses clearTimeout to avoid memory leaks on successful fetch
- Provides a clear error message when timeout occurs
- Properly propagates the original error when fetch fails for other reasons

Fixes #2027
