Add or update translated strings in the CS Demo Manager UI using LinguiJS. Use when adding user-visible text, labels, placeholders, error messages, or any string that should be localized. Handles Trans, useLingui, Plural, msg macros, context disambiguation, and the extract workflow.
Use when you need to communicate between two processes — renderer, server, main, or Counter-Strike — whether adding a new message, handler, push event, or IPC channel.
