Add 国服 (Simplified-Chinese) item-paste translation

Lets players paste an item copied from the Simplified-Chinese (WeGame / 国服)
PoE2 client and have PoB parse it, by translating the paste to the English
item-paste text the parser already expects. No parser changes — a thin hook in
the Item constructor runs the translation before sanitiseText(); it is a no-op
when the text contains no CJK, so English pastes are completely unaffected.

What it translates: item class, rarity, base type, unique name, properties
(quality/spirit/sockets/item level + weapon & defence stats), requirements,
explicit/implicit/rune/desecrated mod lines (via the client's StatDescriptions,
with (min-max) range + (augmented) stripping), flask/charm charge & duration
lines, granted skills, anointments (配置 X -> Allocates X, incl. passive-node
names), and affix annotations ({ 前缀属性 "name" (等阶：N) } with the affix name
translated so PoB fills prefix/suffix tiers).

Data: src/Data/ChineseTranslation.lua is generated by the self-contained
datamine toolchain in tools/cn-translate/ (Node + pathofexile-dat) from the
WeGame client, joining en<->zh on the language-independent metadata Id. NOTE:
regeneration requires the 国服 client (the only source of the SC strings), so it
can't be reproduced from the international GGPK — see tools/cn-translate/README.md.

Tested: spec/System/TestChineseItemParse_spec.lua round-trips a corpus of real
国服 pastes through the parser (base recognised; affix tiers populated; mods
resolved). ~94.5% line coverage on the corpus (remainder is procedural rare
names + unique flavour, which PoB ignores). Baseline item-parse specs unaffected.
