feedback5: merge W5S — i18n phase 2: every player-facing Chinese literal in the client, shared and server goes through t() / tParts() / N_() (1 128 → 0; en.json 1 015 entries), server-sent data texts show the English record, a language switch refreshes cached names; test/i18n.test.js enforces extract 0 / check --strict over the whole tree; Chinese output unchanged (per-file render proof); golden unchanged
