BASE 44 ORDER: Implement Q8 quantization for E8 root vectors in Excalibur lattice engine — E8 Intelligence Research

Andrew's order (Base 44 console): [SELF-BUILD from enhancement #598] Implement Q8 quantization for E8 root vectors in Excalibur lattice engine: replace float64 storage with int8, add dequantize on load, update vector ops to use Q8 dot product, benchmark against replay benches. MERLIN: Understood, Andrew. You want to replace float64 storage with int8 for E8 root vectors, add dequantization on load, update vector ops to use Q8 dot product, and benchmark against replay benches. The swarm will now fork the Excalibur engine branch, implement the Q8 quantization and dequantization routines, modify the vector operations for Q8 dot product, and run the replay benchmarks to verify performance gains.
