        Performance Optimizations
        - GPU backend activation
          - Multi-backend support: Metal, BLAS, CUDA, Vulkan, CPU
        - New backend discovery API:
          - Lugh::available_backends() - List all available backends
          - Lugh::backend_count() - Get backend count
          - Lugh::backend_info($name) - Get backend metadata
          - Lugh::backend_available($name) - Check availability
          - Lugh::best_backend() - Get recommended backend
          - Lugh::has_metal() / Lugh::metal_available() - Metal support
        - Backend selection parameter for Lugh::Inference->new(backend => $name)
        - Memory pools for efficient repeated inference:
          - create_memory_pool() - Create reusable compute resources
          - forward_with_pool($pool, \@tokens) - Forward pass with pooled resources
          - Lugh::MemoryPool class with reset() and backend() methods
        - Batch processing for multiple sequences:
          - forward_batch(\@sequences) - Process multiple token sequences
        - New comprehensive performance test file t/09-performance.t
        - Full documentation for new APIs Lugh/Lugh::Inference

0.04    2026-01-18
        - Added KV Cache support for efficient incremental decoding - Lugh::KVCache
        - Lugh::Inference - New create_kvcache() and forward_with_cache() methods
        - New test file t/08-kvcache.t

0.03    2026-01-18
        - Added generate() method for multi-token autoregressive generation
        - Added sample_top_k() method for top-k sampling
        - Generation supports: greedy, top_p, top_k, temperature, streaming callbacks
        - Added EOS token stopping and callback-based early stopping
        - New test suite t/07-generate.t with 22 tests including exact output validation

0.02    2026-01-17
        - Added Flash Attention support via ggml_flash_attn_ext()
        - Added support for tied embeddings (output.weight = token_embd.weight)
        - Bundled TinyStories-656K test model (749KB) for self-contained tests
