Common forwarded flags:
  --auto                           Enable tool-backed agent mode with auto-approvals
  --json                           Emit summary JSON

  --continue                       Continue the most recent session for this workspace
  --output-format <FORMAT>         Output format: text or stream-json

Plain `codewhale exec` is a one-shot model response. Use `--auto` for
non-interactive filesystem/shell tool use, matching the supported automation
path used by stream-json wrappers.

This command forwards to the TUI runtime. `run` invokes tool-backed agent mode

working-tree diff. `export` only writes the current diff.
