i18n_use re-read and re-parsed the .po on every change of language (ev_SettingsChanged, SetLang) and dropped the old tables for good: the play of 22 minutes left lines_of 650 KB, fs_read_text 409 KB, PoEntry 113 KB and unquote 273 KB unreachable, and three of its @alloc_ok sites were declared but unbounded. Each language's tables are now filed by index once built (tables.ludic, I18nTables) and put back by reference; a new probe (i18n_init) or a different file for a code (lang_add) reads it again. Test: a language switched back to is its kept tables, not its file read again; a new probe reads it (9 tests pass). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
