Reuven 72493c7abd feat: Complete LLM system with Candle, MicroLoRA, NEON kernels
Implements a full LLM inference and fine-tuning system optimized for Mac M4 Pro:

## New Crates
- ruvllm-cli: CLI tool with download, serve, chat, benchmark commands

## Backends (crates/ruvllm/src/backends/)
- LlmBackend trait for pluggable inference backends
- CandleBackend with Metal acceleration, GGUF quantization, HF Hub

## MicroLoRA (crates/ruvllm/src/lora/)
- Rank 1-2 adapters for <1ms per-request adaptation
- EWC++ regularization to prevent catastrophic forgetting
- Hot-swap adapter registry with composition strategies
- Training pipeline with LR schedules (Constant, Cosine, OneCycle)

## NEON Kernels (crates/ruvllm/src/kernels/)
- Flash Attention 2 with online softmax
- Paged Attention for KV cache efficiency
- Multi-Query (MQA) and Grouped-Query (GQA) attention
- RoPE with precomputed tables and NTK-aware scaling
- RMSNorm and LayerNorm with batched variants
- GEMV, GEMM, batched GEMM with 4x unrolling

## Real-time Optimization (crates/ruvllm/src/optimization/)
- SONA-LLM with 3 learning loops (instant <1ms, background ~100ms, deep)
- RealtimeOptimizer with dynamic batch sizing
- KV cache pressure policies (Evict, Quantize, Reject, Spill)
- Metrics collection with moving averages and histograms

## Benchmarks
- 6 Criterion benchmark suites for M4 Pro profiling
- Runner script with baseline comparison

## Tests
- 297 total tests (171 unit + 126 integration)
- Full coverage of backends, LoRA, kernels, SONA, e2e

## Recommended Models for 48GB M4 Pro
- Primary: Qwen2.5-14B-Instruct (Q8, 15-25 t/s)
- Fast: Mistral-7B-Instruct-v0.3 (Q8, 30-45 t/s)
- Tiny: Phi-4-mini (Q4, 40-60 t/s)
