Greptile Summary

This PR replaces the hard-coded rank-3 and rank-4 print loops in InternalPrint with three generic recursive template helpers (PrintDefaultSlices, PrintMlabCat, PrintPythonRecursive) and removes the MATX_STATIC_ASSERT(Op::Rank() <= 4, …) gate, so all three print formats now work for any tensor rank ≥ 3.

• include/matx/core/print.h: Adds PrintIndexArray, GetPrintExtents, and three format-specific recursive helpers; the else branch in InternalPrint dispatches to them for rank ≥ 3 while leaving the dedicated 0-D, 1-D, and 2-D paths untouched.
• test/00_io/PrintTests.cu: Adds DefaultTest5D, MlabTest5D, and PythonTest5D with exact string comparisons, verifying all three format paths for a rank-5 tensor.
• test/00_operators/print_test.cu / examples/print_styles.cu: Smoke-test and example usage extended to a 5-D tensor in all three formats.

Confidence Score: 5/5

Safe to merge — the refactor is self-contained to the print subsystem, all three format paths are verified by exact-string tests for the new 5-D case, and the 3-D/4-D test suite continues to validate backward-compatible output.

The generic recursive helpers produce output that is character-for-character identical to the removed hand-rolled loops for ranks 3 and 4, as confirmed by the existing exact-match tests. The new helpers extend cleanly to rank 5+, covered by three new exact-output tests. No incorrect indexing, off-by-one, or dangling-reference issues were found during detailed tracing of the template recursion and indentation logic.
