The system font scan also reads the font files CoreText has available
(core-text's collection of all available fonts, safe API), so fonts that
Adobe Fonts, RightFont and other font managers register from their own
folders are cataloged. Files the font folders already hold are read once;
paths that lead to no file are skipped. FontDb::global serves the desktop
app and designcraft-cli alike; the scan stays in the background.
Fixes#261, #327.
Characters the primary font lacks try a fallback chain by language
before the language-blind search: Japanese (the craft-fonts Japanese
faces first, Mincho first), Simplified Chinese (also plain Chinese),
Traditional Chinese and Korean each list their macOS, Windows and Linux
system families. Hangul, kana and Bopomofo pick their language's chain
whatever the character language; ideographs and CJK punctuation follow
it, and keep today's fallback without a CJK language. Chain families
load from the system font catalog the first time they are needed.
designcraft_fonts::testing (feature `testing`) builds synthetic fonts
with a given family name and coverage for tests.
Port the CJK1 and AR1 changes from 3ecdb78 and de83cdc onto current main. Resolve translation and font-stack conflicts by retaining main localization and craft-fonts integration while preserving all typesetting code, tests, and documentation.
Validation: all six CI gates passed, including 616 tests and WASM checks.
