/**
 * Cursor CLI Reviewer Tests (#1960)
 *
 * Verifies that /gsd-review includes Cursor CLI as a peer reviewer:
 *   - review.md workflow contains cursor detection, flag parsing, self-detection, invocation
 *   - commands/gsd/review.md command file mentions --cursor flag
 *   - help.md lists --cursor in the /gsd-review signature
 *   - docs/COMMANDS.md has --cursor flag row
 *   - docs/FEATURES.md has Cursor in the review section
 *   - i18n docs mirror the same content
 *   - REVIEWS.md template includes Cursor Review section
