- Covers inference with and without cache and with sampling (top-k, top-p)
- Includes test for max sequence length (should raise ValueError)
- Verifies output shape and absence of dtype errors for the mask logic
- Minimal config and random data ensure tests are fast and robust

- Used True/False for mask/scatter instead of 1/0, ensuring correctness across PyTorch versions.
- Fixed RuntimeError: masked_fill_ only supports boolean masks, previously raised by uint8-masks in new PyTorch.
- Backward compatibility maintained: code works on PyTorch >=1.2 and for old clusters (via the else branch).
Motivation: Fixes sampling errors for all modern PyTorch users while keeping research code usable on old infra.

This is a partial refactor - attention components are now shared, but decoder remains LLaMA-specific due to different normalization and activation requirements.
