fix: improve binary copy and chmod in Dockerfile

- Copy weed binary explicitly to /usr/bin/weed
- Run chmod +x immediately after COPY to ensure executable
- Add ls -la to verify binary exists and has correct permissions
- Make weed_pub* and weed_sub* copies optional with || true
- Simplify RUN commands for better layer caching
