When TERMINAL_ENV is not 'local', execute_code now ships the script to
the remote environment and runs it there via the terminal backend --
the same container/sandbox/SSH session used by terminal() and file tools.
Architecture:
- Local backend: unchanged (UDS RPC, subprocess.Popen)
- Remote backends: file-based RPC via execute_oneshot() polling
- Script writes request files, parent polls and dispatches tool calls
- Responses written atomically (tmp + rename) via base64/stdin
- execute_oneshot() bypasses persistent shell lock for concurrency
Changes:
- tools/environments/base.py: add execute_oneshot() (delegates to execute())
- tools/environments/persistent_shell.py: override execute_oneshot() to
bypass _shell_lock via _execute_oneshot(), enabling concurrent polling
- tools/code_execution_tool.py: add file-based transport to
generate_hermes_tools_module(), _execute_remote() with full env
get-or-create, file shipping, RPC poll loop, output post-processing
- Merge _init_persistent_shell + _start_persistent_shell into single method
- Move execute() dispatcher and cleanup() into PersistentShellMixin
so LocalEnvironment and SSHEnvironment inherit them
- Remove broad except Exception wrappers from _execute_oneshot in both backends
- Replace try/except with os.path.exists checks in local _read_temp_files
and _cleanup_temp_files
- Remove redundant bash -c from SSH oneshot (SSH already runs in a shell)
