Addressing reviewer feedback (smnnlt)

• Streamlined test suite: reduced from ~600 to 373 focused assertions; all tests pass with zero warnings and zero skips
• Replaced expect_true(is.data.frame()) with expect_s3_class(), expect_equal(length()) with expect_length() throughout
• Consolidated fragmented test files into per-feature test files
• Removed purrr from package dependencies (was only used once via the superseded purrr::transpose()); R CMD check now passes with 0 errors, 0 warnings
