Remove the unconditional NVRTC waiver from the renamed example so CI can exercise its real execution path again. While re-enabling it, replace the standalone pytest.skip() checks with requirement_not_met() and simplify the platform gating. The waived code path had been hiding several Python-side runtime bugs that required these fixes: - replaced the invalid C-style %d f-string formatting - fixed gen_tridiag() variable shadowing so the CSR row-offset array is actually populated - passed the computed dynamic shared-memory size into cuLaunchCooperativeKernel() and made that size integer-valued - stopped overwriting managed-memory pointer variables with loop indices before kernel launch and cleanup - cached the residual before freeing dot_result, which removed the teardown segfault Made-with: Cursor
QNX is an operating system rather than a machine architecture, so checking platform.machine() can miss the requirement_not_met() path on QNX hosts. Use platform.system() so the example is waived consistently on that platform. Made-with: Cursor

This PR started out as a humble attempt to eliminate the only remaining
pytest.skipin our examples (similar to #1861), but then turned into a bigger-than-anticipated bug-fix project.See commit messages for full details.
