crucible v0.1: CPU inference library for PyTorch .pt state dicts, in pure Zig

- restricted pickle VM (whitelisted globals — cannot execute arbitrary
  Python, unlike torch.load)
- zip container reader (store + raw-deflate)
- Tensor views: dtype/offset/sizes/strides, f32 materialization
- layers: conv2d f32x8 FMA, linear, relu, maxpool2, adaptiveAvgPool2d,
  softmax, padInput
- examples/stripsolver: real .pt forward, 3777 @ 1.0
