* feat(docs): mirror every docs/ page in all 65 locales
Extends the documentation mirrors from the 22-page core set (#13940) to
every Markdown page under docs/: 152 sources x 65 locales = 9,880 mirrors
(6,208 new), language bars rewritten for the full locale list, state
adopted so the blocking drift gate now covers all 152 pages.
run-translation.mjs: an oversized block made only of table rows or list
items (PROVIDER_REFERENCE.md 244-row table, FREE_TIERS.md 71-item list) is
cut at item boundaries and rejoined without a blank line — the single
16-40 KB request outlived the backend socket for verbose scripts. 48
older mirrors whose tables had lost rows were retranslated with --force.
* docs(i18n): refresh mirrors for the sources the base changed since the branch cut
Section-level retranslation of the 29 docs (and README.md) whose source
or mirrors moved on release/v3.8.51 during the run, then state adoption;
the drift gate is green again on the merged tree.
