Root cause: _WORKDIR was hardcoded to "/home/user" which doesn't exist
in AWS AgentCore Code Interpreter environment (actual pwd is
/opt/amazon/genesis1p-tools/var). Every command was prefixed with
"cd /home/user && ..." which failed silently, producing empty stdout.
Fix:
- Default _WORKDIR to "/tmp" (universally available)
- Auto-detect actual working directory via "pwd" during
_construct_environment and override _WORKDIR dynamically
Verified: echo, python3, uname all return correct stdout.
