Fix strace-macos to work inside Nix devShells - #46

Conversation
When inside a Nix devShell with default stdenv, /usr/bin/python3 resolves to Nix's Python which lacks LLDB bindings, causing strace to fail with "Failed to load LLDB Python module" error. This occurs because Nix sets DEVELOPER_DIR to point to its SDK, making system tools like xcrun find Nix's Python instead of macOS system Python. Solution: Use Command Line Tools Python directly at its fixed path (/Library/Developer/CommandLineTools/usr/bin/python3) which always has LLDB bindings and works reliably in any environment. Fixes: #44
