refactor: standardize method naming and clarify log messages

Improves code consistency by standardizing method naming conventions and
clarifying log messages across builders.

Changes:
- Renamed buildClientLibrary() to createClientLibrary() in BaseBuilder to match
  the convention where "create" is used for protected/shared methods
- Updated all callers in StandaloneBuilder and VercelBuildOutputAPIBuilder
- Clarified log messages in StandaloneBuilder by removing "Vercel API" prefix
  since this builder is framework-agnostic

This establishes a clear pattern:
- Public/template methods in subclasses: build* (buildStepsFunction, etc.)
- Protected/shared methods in BaseBuilder: create* (createStepsBundle, etc.)
