#
# This stage builds and compiles framework dependencies including:
# - SGLang inference engine with CUDA support
# - DeepEP and NVSHMEM
# - All necessary build tools and compilation dependencies
# - Framework-level Python packages and extensions
#
# Use this stage when you need to:
# - Build SGLang from source with custom modifications
# - Develop or debug framework-level components
# - Create custom builds with specific optimization flags
