Summary description: A LuaTeX based package to handle Chinese text typesetting

Announcement text: ------------------------------------------------------------------------

luatex-cn 0.4.1 -- first update on CTAN since 0.3.1.

luatex-cn typesets Chinese with LuaLaTeX in both writing directions:
faithful reproduction of classical (guji) page layouts, and modern
Chinese typesetting following the W3C Requirements for Chinese Text
Layout (clreq).

Highlights since 0.3.1:

* Unified entry point: \usepackage{luatex-cn} now loads the new
horizontal clreq pipeline by default (options are passed through,
e.g. [style=taiwan]); the [vertical] option or any ltc-* document
class selects the vertical engine, with 0.3.x semantics unchanged.

* Horizontal clreq pipeline (new): CJK-Western spacing (1/4 em,
compressible to 1/8, stretchable to 1/2, with the exceptions clreq
specifies), punctuation width adjustment with Mainland China /
Taiwan / untouched presets, quote-style conversion, four-level
line-breaking prohibitions and non-separation rules, intra-line
compression/stretching in clreq priority order, half-width
punctuation at line end, hanging punctuation, interlinear marks
(proper-name mark, book-title mark, emphasis dots), word-aligned
pinyin ruby, paragraph/page controls (orphan handling, hanging
indentation, last-line alignment).

* Vertical clreq conformance: 1/4 em CJK-Western boundary spacing,
\Sideways (rotated Western text), \CombineUpright (tate-chu-yoko),
hanging punctuation at column end, clreq-conformant emphasis dots
per document class.

* A shared rules kernel used by both directions (single source for
the clreq punctuation table, space-distribution solver and
prohibition rules), a published conformance matrix
(doc/CLREQ-CONFORMANCE.md), and 119 PDF-content-stream metric
assertions run in CI.

* Installation-free fonts: \setmainfont with a bare font file name,
registry aliases, and a helper script that installs fonts into
TEXMFHOME without touching the system font library.

* Typesetting additions from the 0.3.x series: tables with
cross-page support and horizontal bands, European-style genealogy
charts, gongche (traditional musical notation), illustration
pages, colophon (paiji) boxes, multi-level headings, and a modern
vertical book layout in the style of Zhonghua Shuju (footnotes,
first-line indentation, alternating running heads).

* 0.4.1 fixes: Western words in annotations/textboxes are no longer
hyphenated and mis-columned; in fixed-grid mode \Sideways now
sizes rotated words by their advance width.
