w1n5t0n c646872e42 feat(playground): wire WasmIML methods into debug probe
Add evalLoss, inferBatch, and getLayerStats to the window.__nisps
debug probe so Playwright tests and dev console can access the new
WasmIML capabilities. InputHeatmap (Phase 3) is not yet wired into
a-app.js, so batch inference heatmap integration is deferred.
