The old main.cpp (TEST target) called APIs that no longer exist (DeepStack::load()/loadWeights()/loadTrainingBatch() with no args, Layer::upDownPass()) -- it hadn't compiled against the current AStack/ Layer API in a long time and was a manual smoke-test script, not an actual test suite. Replace it with a small dependency-free runner matching this repo's existing no-framework style: for each named project, load it, load weights and training batch, run a full up-pass/down-pass reconstruction via DeepStack::upDownPass, and check the reconstruction error is finite and beats the trivial per-feature-mean baseline (a project-agnostic sanity bound, rather than a hardcoded threshold). Prints PASS/FAIL per project. Starting coverage: 1-hot, prims, norb_small_16h_v2, mnist_2. 3/4 pass; norb_small_16h_v2 fails because it has no saved weight files at all (only .prj/.training.dat/.test.dat) -- a pre-existing gap in that fixture's data, not a bug introduced here.
