This PR adds the frame operations getNames and setNames.
Changes:
Tests:
The propagation tests verify that column names are preserved correctly during frame operations. The covered operations are cbind, rbind, and slice.
The tests use frame dimensions ranging from 10 to 1000 columns.
Note:
I observed unusual column-name propagation behavior for cbind on wider frames around 3000 columns. I left this case out of the regression tests to keep the PR focused on getNames/setNames and the CP runtime scope.
