feat(review): add Cursor CLI self-detection and complete REVIEWS.md template (#1960)

Add CURSOR_SESSION_ID env var detection in review.md so Cursor skips
itself as a reviewer (matching the CLAUDE_CODE_ENTRYPOINT pattern).
Add Qwen Review and Cursor Review sections to the REVIEWS.md template.
Update ja-JP and ko-KR FEATURES.md to include --opencode, --qwen, and
--cursor flags in the /gsd-review command signature.
