) MAX_DEPTH=32000 required ~7.2 MB of C stack before switching to iterative mode — too close to the 8 MB default on Linux and over the limit on some CPAN smoker and container environments. This caused SEGV in t/10-deep_recursion.t on multiple CPAN testers. Lower MAX_DEPTH to 4000 (~900 KB stack), which is safe on any reasonable system. The iterative fallback handles deeper structures correctly. Also lower the test's deep_target from 35000 to 5000: still exceeds MAX_DEPTH/2 (2000 nesting levels) to exercise both recursive and iterative paths, but avoids overflowing Perl's own recursive SvREFCNT_dec during structure cleanup.
