fix(yggdrasil): localize town crowd names

[CloudeaSoft]

Town Crowd NPCs referenced name localization keys without corresponding text entries. Add dedicated Mods.Everglow.TownCrowds.hjson files for English and Simplified Chinese and point the name selector and existing test at that namespace.

Retain fixed, seeded names and add 12 Chinese names of 2–4 characters with English pinyin equivalents, bringing the pool to 44 names. Both languages cover every candidate.

Validation:

• dotnet build --verbosity quiet /p:WarningLevel=0 — passed (10 existing dependency warnings, 0 errors).
• dotnet test --no-build --no-restore --verbosity quiet /p:WarningLevel=0 — all 759 tests passed.
• Hjson parsing, all 44 name keys in both languages, 2–4 character Chinese additions, byte-level UTF-8 BOM check, and git diff --check — passed.
• In-game name rendering has not been manually verified.
