Add RAID 0 production deployment suite

- Linux mdadm RAID 0 deployment (4 NVMe, 28 GB/s)
- Performance test scripts and configuration
- WebDAV + RAID integration documentation
- CLI WebDAV command integration in main.rs
- Complete deployment checklist (1685 lines)

Testing verified: RAID 0 stripe algorithm works correctly
