Implementation

• Added default profile for existing smythos service (uses pre-built AMD64 image)
• Added native profile for new smythos-native service (builds locally for native architecture)
• Updated README.md with native build instructions
• Updated DOCKER_COMPOSE.md with native build instructions and troubleshooting

Usage

Default (AMD64, emulated on Apple Silicon):

docker compose up -d

Native ARM64 build (Apple Silicon):

docker compose --profile native up -d

Benefits

• Zero breaking changes - default behavior unchanged
• Optional native builds for Apple Silicon users
• Better performance on ARM64 (no emulation overhead)
• Clearer documentation for architecture-specific issues

Fixes #[302]

Thanks for your PR @pwgraner !

I think for this issue, we just need to adjust our build CI pipeline from our side to build for multi-arch.
Your solution enables building the image locally but I think we do not need to include local builds in our docker compose yaml
