fix(scripts): use import alias in update.mjs

Fixes linting errors in CI caused by direct '@socketsecurity/lib/*'
imports. The update script was using direct package imports instead of
the '#socketsecurity/lib/*' alias pattern used by all other scripts.

Changes:
- Changed '@socketsecurity/lib/*' to '#socketsecurity/lib/*'
- Converted default imports to named imports for consistency
- Aligns with import pattern used across all other scripts

This resolves ESLint import-x/no-unresolved and n/no-missing-import
errors that prevented the lint job from passing in CI.
