M9: distinct zh label for Revert; translations are our own

Revert no longer shares Undo's Simplified Chinese label. Drop the
comments and ROADMAP wording that tied terminology to a vendor's help.

 - Transparency flattener (`file.exportPdf {flatten: high|medium|low|ppi}`, Edit ▸ Transparency Flattener Presets): each object involving transparency becomes an opaque image of its area over what's beneath it, so everything else stays vector (spreads with transparent parent items are rasterised whole).
 - Video and sound (place .mp4/.mov/.webm/.mp3/.wav…, `media.options/get`, Media panel): media frames show a poster or placeholder on screen, in print and in PDF, and export as HTML5 `<video>`/`<audio>` in EPUB. Interactive PDF export (`file.exportPdf {media: true}`, File ▸ Export PDF (Interactive)) embeds each file and plays it in a Screen annotation through a rendition action (controls, loop, play on page load). No in-app playback.
 - Right-to-left text (World-Ready basics): right-to-left runs are shaped right to left, lines are reordered by the Unicode Bidirectional Algorithm (matched against the reference implementation), Paragraph Direction (`type.para {direction}`, Paragraph panel, IDML ParagraphDirection, EPUB `dir`). Digits (`digits`: Default, Arabic, Hindi, Farsi, Native by language; Character panel for right-to-left text; IDML DigitsType) draw 0–9 in another script. Kashidas (`kashidas` paragraph attribute, on by default): justified Arabic lines stretch at one join per word (after seen/sad when possible, never inside lam–alef) with a drawn tatweel before word spaces widen. Carets follow the drawing: the caret before a right-to-left glyph sits at its right edge, arrow keys move as drawn (by words in the line's direction), clicks find the nearest drawn caret position and selections highlight the selected glyphs. Binding: Right to Left (Document Setup, `layout.documentSetup {binding}`, IDML PageBinding) makes page 1 a left page and lays spreads out right to left.
-- Interface language (Edit ▸ Interface Language, `app.language`): German, French, Spanish, Japanese, Simplified Chinese and Arabic menu titles, common menu items and panel names (our own translations). Common dialog, panel and tooltip labels are also localized, with English fallback for untranslated strings. Arabic translations cover every key in the shared interface translation table, including menu commands and utility labels. Chinese and Arabic feature terminology is checked against public Adobe help where verified; project-specific labels remain original translations. The Type menu's Story Direction, Horizontal/Vertical, Tate-Chu-Yoko, Ruby… and Kenten are translated too. Arabic labels use Unicode bidi run ordering and contextual shaping; welcome and new-document form layouts follow RTL direction independently of document binding. CJK and Arabic glyphs come from [craft-fonts](https://github.com/storytold/craft-fonts) when built with `CRAFT_FONTS_DIR` (all releases): BIZ UDPGothic and Noto Sans CJK SC for the UI (Chinese forms first in the Chinese interface), Noto Sans Arabic, and Mincho for Japanese documents (the web build embeds BIZ UDPGothic only); otherwise from system fonts.

 - Page transitions (`page.transition/transitions`, Page Transitions panel): twelve transition types with speed and direction per spread, written into exported PDFs as `/Trans` entries through an incremental update.
 - PDF/X-4 export (`file.exportPdf {standard: "x4"}`): an output intent with our own Generic CMYK ICC profile (lut16 tables generated from the parametric press model), GTS_PDFXVersion in Info and XMP, and built-in PDF/X-4 checks reported as warnings. qpdf finds no errors in the result.
 - EPS place: placed at its (high-resolution) bounding box and shown, printed and exported through its TIFF preview, or a placeholder when it has none. PostScript itself isn't interpreted.
