Frédéric DesbiensandCopilot 30e1d491a9 Added copyright headers to files missing them
Applied the standard MIT license header to all project-owned C, header,
assembly, shell, and Python files that were missing a copyright notice.
Third-party, toolchain startup, and auto-generated files were excluded.
