Roadmap and README: Japanese interface and initial vertical type

The appended Interface localization section moves into the roadmap's structure: a
Shipped so far entry, the Type advanced row (45%, CJK composition left), the gap list,
the inventories (16 stubbed menu items; Touch Type the only missing tool) and totals
recomputed from the parity table (75.3%, 211–332 h to feature parity); README Status
follows.

 - 3D and Materials;
 - the Photoshop-style raster effects (Effect Gallery);
-- vertical and CJK type;
+- CJK composition for vertical type (vertical type itself has initial support, with a Japanese interface);
 - Variables and scripting;
 - an interaction-fidelity pass covering every tool's modifiers and small behaviours;
 - packaging for Windows and Linux.

 ## How to update this file
 After each milestone task lands, update the status column and remaining estimates, and move items into "Shipped so far". Keep estimates honest: re-derive them from what remains, never from wishful velocity.

-### Interface localization
-
-The VectorCraft > Language submenu switches English/Japanese and persists in UI state (`app.language {lang: en|ja}`). Both macOS native and in-window menus translate core labels; the native menu refreshes after a language change. Bundled OFL Shippori Mincho provides Japanese UI/document glyph fallback without system fonts. Untranslated labels use English. Broader dialog/panel translation and vertical/CJK composition remain open.
-
-Vertical point/area/path type tools now create persisted vertical text. Type > Orientation
-switches existing objects. Point/area text flows down columns progressing right to left, with
-upright Japanese glyphs and vert/vrt2 alternates. Hit testing, caret/selection and arrow keys
-use the writing axes. Vertical path type turns glyphs across the baseline path. SVG exports
-vertical text as outlines to preserve appearance; native documents retain editable text.
-This is initial vertical support, without kinsoku, ruby, tate-chu-yoko, vertical font metrics
-or full mixed-script Unicode vertical orientation.
