- Create assembly/vm.ts with full RandomX VM implementation
- 256 instructions, 2048 iterations per hash
- Native u64/f64 operations in WebAssembly
- Full mode dataset lookups (2GB pre-computed)
- Update miner to use WASM VM for full mode
- mining-worker-asm.js uses pre-compiled WASM
- ~32 H/s per thread (4x faster than light mode)
- 8 threads achieves ~260 H/s
- Clean up redundant code
- Remove mining-worker-full.js (old JIT approach)
- Consolidate 'asm' mode into 'full' mode
