* Mirror the shell for right-to-left UI languages (DIST-220-4)
Arabic, Hebrew, Persian and Urdu read right to left, but the window's
chrome was hard-wired left to right, so an RTL catalog (#2505) would
put Arabic labels into a left-to-right layout.
The reading direction now follows the language code
(i18n::dir_for_code: ar, ckb, dv, fa, he, ps, sd, ug, ur, yi), so a
catalog needs no extra setting and the LANGUAGES rows are unchanged.
In a right-to-left language the shell mirrors:
- the menu bar starts at the right with File; menus open under their
title's right edge, and the arrow keys step through them in screen
order
- the toolbox docks on the right, the panel dock and its rail on the
left; tool flyouts open towards the canvas and their corner marks
and the header chevrons follow
- the title, options and status bars read from the right, with the
workspace controls and the Fit/progress group at the left end; the
title and window-drag gap use the free span between them
New module direction.rs holds the helpers (start_panel/end_panel,
row/trailing layouts, horizontal_centered, the popup alignment). Left
to right, every change lays out as before.
No RTL catalog ships yet, so PHOTOCRAFT_UI_DIRECTION=rtl forces the
mirrored layout for review (read once, native only). Panel interiors,
dialogs, menu rows, submenus and document tabs stay left to right, and
egui still draws UI labels without Arabic shaping or bidi reordering;
docs/localization.md and the parity docs say so.
Adds Lucide's chevron-left (the status bar's info menu arrow points
left in RTL; Timeline's Previous frame button asked for it too and drew
the fallback square).

* Localization docs: egui shapes Arabic words; what's missing is a font and bidi word order
egui 0.36 shapes right-to-left runs with HarfRust, so letters join within
a word. The gaps are an Arabic fallback font in the UI and paragraph bidi
(words are placed left to right; emilk/egui#8576, #8577).
