fix(code): bind headless basic tools to workspace, harden lifecycle

- Bind basic file/shell tools (read/write/list/execute) to --workspace via
  Workspace containment (fail-closed), matching the edit group, so an
  auto-approved headless run cannot escape the configured workspace.
- Move workspace resolution + tool loading inside the protected try/finally in
  _run_print_code so init failures still emit the JSON error envelope and always
  run cleanup_runtime().
- Use a private mktemp log in the terminal-bench example instead of a
  predictable /tmp path; drop the stale log_path metadata.
- Add --dangerously-skip-approval to the opt-in real-agent write test and a
  fast regression test for basic-group workspace containment.
