Fixes#83901. Honors Commander negated option handling for ACP prompt-prefix forwarding and adds focused CLI regression coverage. Verified with Crabbox AWS cbx_1689d0ad78e9 run run_a406418db6fe and Real behavior proof run 26127392365.
Summary:
- The PR changes `openclaw acp client` error handling to use `formatErrorMessage`, adds a plain-object rejection regression test, and adds a changelog entry.
- Reproducibility: yes. Current main visibly sends `openclaw acp client` caught errors through `String(err)`, ... catch already uses `formatErrorMessage`; I did not run a live failing ACP server in this read-only review.
Automerge notes:
- PR branch already contained follow-up commit before automerge: fix(cli): format acp client errors with formatErrorMessage (#83904)
Validation:
- ClawSweeper review passed for head 69ef0e7270.
- Required merge gates passed before the squash merge.
