Pull Request Overview

This PR refactors test data management by moving test datasets from R package data (.rda files) to test-scoped RDS files. The changes improve test isolation by making test data local to the test suite rather than part of the package's exported data objects.

Key changes:

• Convert .rda test data files to .rds format and move to test scope
• Update data loading from load() to readRDS() calls in test files
• Remove exported data documentation from the package
