Term ooc covariance tsmm

[122Astha]

I added the initial OOC covariance test setup for cov(A, B). The test creates dense and sparse vector inputs, runs the covariance script once as the CP reference and once with -ooc, then compares the results.

Currently both dense and sparse OOC tests fail for the expected Week 1 reason: SystemDS generates an OOC cov instruction, but OOCInstructionParser does not support Covariance yet. The key error is: “Invalid OOC Instruction Type: Covariance”. This confirms the test-first setup is working and identifies the missing implementation/wiring.

Thanks for the first PR, @122Astha. I’d suggest working on the covariance implementation before opening a PR. It isn’t necessary to open PRs just to introduce failing test cases.

Please configure your IDE to use tabs instead of spaces (and remove hello.dml).
