Execute Python code in a sandboxed Docker container. Pre-installed packages: pwntools, capstone, keystone, unicorn, lief, yara, pycryptodome. Session state (variables, imports) persists across calls.

Destroy the Python sandbox container and clear all session state. The next python_eval call will create a fresh container.

Upload a file into the sandbox container's /tmp directory. Useful for dropping binaries or samples for Python analysis.

List files in the sandbox container's /tmp directory (output of ls -la /tmp).

Read a file from the sandbox container's /tmp directory and return its base64-encoded content. Maximum file size: 10MB.
