- pr +commits: list commits of a pull request
(GET /pulls/:id/commits)
- pr +check-merge: pre-flight check_can_merge before creating a PR.
Detects same-branch no-ops and existing duplicate merge requests,
including the cross-fork case via --fork-project-id (which also
sets is_original, matching the server's duplicate lookup).
Production-verified on gitlink.org.cn: commits listing, a
'can merge' pass, and duplicate detection that points at the
existing PR. 2 unit tests, README examples, bilingual i18n keys.
