Fallback to shell execution when sandbox fails for library-dependent Python code

From the source SKILL.md

When execute_code_sandbox fails for Python code that depends on external libraries, use run_shell with a heredoc Python script as a reliable fallback. The shell environment typically has better access to installed packages and system configuration than the sandbox.
