Collapse resolveRelativePath and resolveAbsolutePath into a unified
resolvePath function, extracting common library matching logic into a
new findInLibraries helper method.
This eliminates duplicate code (~20 lines) while maintaining clear
separation of concerns: resolvePath handles path normalization
(relative vs absolute), and findInLibraries handles library matching.
Update tests to call resolvePath directly with appropriate parameters,
maintaining full test coverage for both absolute and relative path
scenarios.
