Pull request overview

This PR updates the test suite and parts of the NeuralNet stack (Network/FeedForward/Snapshot) to address failing tests and support the ongoing NDArray/NumPower migration, plus a few small runtime-safety tweaks.

Changes:

Refactors NeuralNet network-related tests and implementations to use FeedForward and new Networks\Base\Contracts\Network.
Adjusts multiple tests for stability/compatibility (expected values, namespaces, updated revisions/params).
Adds small runtime checks (e.g., RBX checksum parsing) and updates config/baselines.

src/NeuralNet/Networks/FeedForward/FeedForward.php:101

$normalizeSamples is initialized to false and never set to true (no setter/constructor param), so the entire normalization branch in infer() plus the normalizeSamples() helper are currently dead code. Either remove this flag/branch, or expose a clear way to enable it (e.g., constructor option or public method) and add coverage for the normalized path.
