/**
 * Tests for review-only piece
 *
 * Covers:
 * - Piece YAML files (EN/JA) load and pass schema validation
 * - Piece structure: plan -> reviewers (parallel) -> supervise -> pr-comment
 * - All movements have edit: false
 * - pr-commenter persona has Bash in allowed_tools
 * - Routing rules for local vs PR comment flows
