Restore lineage between main and internal staging so the next
staging->main promotion (#27436) can merge without conflicts.
main was 2 commits ahead:
- 6ff668c7aa squash-merge of the previous staging->main promotion (#27245)
- 8c9830eef9 feat(xai): add grok-4.3 (#27396), already present on staging
The squash-merge has no shared lineage with the individual commits that
went into staging, which is why git surfaced 13 textual conflicts despite
both sides having the same logical content. Every conflicting file's
main-side change came from 6ff668c7aa only, and the matching staging-side
changes are the post-promotion evolution. Resolved all 13 with --ours
(staging's version is the latest evolution; main's snapshot is stale).
The grok-4.3 entries auto-merged in model_prices_and_context_window.json
and its backup, but were already on staging via an independent commit, so
the net diff vs HEAD is empty for those files.
Net new content from this merge: 12 lines added to
ui/litellm-dashboard/package-lock.json -- npm 11 libc array tags on four
existing entries, no functional impact.
