Register Dhivehi (`dv`, every `dv-*` locale) as a right-to-left interface language with a 2,674-entry Thaana catalog covering every key of the other bundled catalogs. Entries are in typing order and put into display order at load like Arabic; one plural form (`plural_none`). Dates use the Dhivehi names of the Gregorian months and weekdays. Interface text draws with the craft-fonts `Thaa` face (Noto Sans Thaana), added to the font fallback stack and kept in the web build. The release-pinned craft-fonts revision has no Thaana face yet. The catalog is clean-room and AI-assisted; native-speaker review is outstanding. Tests cover registration, persistence, display order, plurals, commands, UI literals, bundled keys, the calendar and glyph coverage. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Update the release craft-fonts pin before enabling Dhivehi Auto resolution.
The release pin 3d9ab3a132ed0eff457e424226a435a901da30d3 has no Thaa face, so ui_thaana_fonts() is empty. Auto maps dv-MV to dv without checking font availability. The web fallback stack has no Thaana coverage, so Dhivehi labels can render as replacement boxes for users whose browser locale is dv-MV. Bump the pin to a revision whose manifest contains a Thaa face before merging.

What this changes
Adds Dhivehi (

Western digits; product and format names stay in Latin.rtl: true, so entries are put into display order at load (bidi::display_rtl), the same way Arabic is. Thaana (U+0780–07BF) already falls inbidi::is_rtl_script's range. Everydv-*locale resolves to it.plural_none. A noun after a numeral keeps its form, so@pluralrows have one form.DATE_LANGUAGESgains the Dhivehi Gregorian month and weekday names (ހޮނިހިރު, 7 މާޗް 2026), which match the catalog's calendar rows.pdfcraft_fonts::ui_thaana_fonts()(craft-fontsThaafaces).
