feat: BitNet full transformer forward pass implementation

- Implemented weight quantization F32 -> ternary {-1, 0, +1}
- Implemented ternary matrix-vector multiplication with scales
- Implemented RMS normalization
- Implemented Rotary Position Embeddings (RoPE)
- Implemented multi-head attention with ternary Q/K/V/O
- Implemented SwiGLU FFN (gate, up, down projections)
- Implemented softmax and SiLU activation
- All 6 unit tests passing

 ### Achievements
-- ✅ BitNet b1.58-large downloaded (2.8 GB)
+- ✅ BitNet b1.58-large downloaded (2.8 GB, 728M params)
 - ✅ Safetensors parser implemented
-- ✅ Model config and tokenizer loaded
-- ✅ 290 tensors identified
+- ✅ Model config and tokenizer loaded (32K vocab)
+- ✅ 290 tensors identified and accessible
 - ✅ Embedding loading verified
+- ✅ **Full transformer forward pass implemented**
+- ✅ **Weight quantization F32→Ternary implemented**
+- ✅ **RoPE, Attention, FFN all implemented**
+- ✅ **6/6 unit tests passing**
+
+### Remaining Work
+- ⏳ Load all layer weights from safetensors
+- ⏳ Wire up full model inference
+- ⏳ Generate coherent text samples
+- ⏳ Benchmark tokens/second
 
-### Blockers
-- ❌ Full transformer forward pass not implemented
-- ❌ Weight quantization scales not extracted
-- ❌ Coherent text not yet generated
+### Files Created
 
-### Recommendation
-Implement full BitNet inference pipeline to achieve coherent text generation. The model is correctly loaded; we just need the complete forward pass with proper ternary quantization.
+| File | Purpose | Lines |
+|------|---------|-------|
+| `bitnet_loader.zig` | Safetensors parser, model loading | ~350 |
+| `bitnet_forward.zig` | Full transformer forward pass | ~400 |
+| `bitnet_inference_test.zig` | Generation test | ~200 |
