Diego Rodrigues de Sa e Souza fcc2dcd1a6 docs(changelog): reconcile the v3.8.51 living section — fold 366 fragments, cover every cycle commit, credit every contributor (#12971) ...

Mid-cycle reconciliation of `## [3.8.51]` against the full cycle range
`release/v3.8.50..release/v3.8.51` (091589089c..d6f315018a, 696 non-merge commits):

- fold the 366 `changelog.d/` fragments into the section (features had been
  landing under `[Unreleased]` because the aggregator appends at the FIRST
  matching heading) and delete them
- drop 25 fragments that duplicate bullets already shipped in `[3.8.50]` /
  `[Unreleased]` (six phantom fragments re-added by branches cut before the
  v3.8.50 aggregation; 19 pre-cycle PR fragments)
- generate one bullet per cycle commit that had no fragment (350 commits:
  44 features / 196 fixes / 91 maintenance, 17 Dependabot bumps rolled up),
  carrying the merged PR link and `— thanks @author`
- credit audit: link every fragment to the PR that actually landed it
  (`git log --diff-filter=A`), fix three `#PR_NUMBER` placeholders and two
  misnumbered fragments (#11845, #11864), credit the recreated PRs to their
  original authors (#11887–#11892 → @MumuTW, #12255 → @backryun,
  #11771 → @Rahulsharma0810), the nine hartmark co-authored fixes, and the
  deleted PR #11370 to @kriptoburak
- add the "Release by the numbers" block, the Top-25 ranking (mailmap +
  GitHub login) and the mandatory `### 🙌 Contributors` hall
  (111 external contributors + maintainer, generated by
  `release:contributors --inject`)
- resync the 41 i18n CHANGELOG mirrors

Gates: check:changelog-integrity OK, check:docs-sync PASS.
