winops_container_exec
Runs commands inside a specified Docker container, piping stdin directly to the process. Returns JSON with stdout, stderr, and exit code for automation.
Instructions
Execute a command inside a Docker container.
Uses subprocess directly (not CMD/PowerShell wrapper) to avoid nested-quoting
issues and list2cmdline mangling. stdin_data is piped directly to the container
command — no need for docker cp + exec dance.
Return Format
