* fix(auth-header): decode _password from base64 for default registry auth
* fix(auth): prepend 'Bearer ' to auth token generated by tokenHelper
* test: skip flaky parallel dlx test on Node 25
* fix(auth): improve tokenHelper Bearer prefix with validation and generic scheme detection
- Throw an error when the token helper returns an empty token instead of
producing an invalid "Bearer " header
- Use a generic auth scheme regex instead of hardcoding only Bearer/Basic,
so other schemes (Token, Negotiate, etc.) are preserved as-is
- Add tests for raw token prefixing, existing scheme preservation, and
empty token error
