Dockerfile.debug

# Fast debug build Dockerfile for load-reth development
# Uses same cargo-chef pattern as production but optimized for iteration speed
# - No cross-compilation (native platform only)
# - Configurable profile (default: release for reasonable speed)
# - Debug symbols preserved for profiling
