/**
* Built-in workflow: `multi_perspective_review`
*
* Reviews a target (file, PR, design doc, plan — passed via args.target) from
* several independent perspectives, then asks an adversarial judge to decide
* what would actually break in practice. Useful for sanity-checking decisions
* before they ship.
*
* Args:
*   - target: what to review
*   - lenses: optional array of { name, angle } to override default lenses
*   - skipAdversarial: when true, skip the adversarial judge phase
