cmux Localization

Use this skill for any user-facing string change.

Hard rules

• All user-facing strings must be localized.
• Use String(localized: "key.name", defaultValue: "English text") for Swift/AppKit/SwiftUI strings.
• Keys go in Resources/Localizable.xcstrings with translations for all supported languages, currently English and Japanese.
• Never use bare string literals in SwiftUI Text(), Button(), alert titles, tooltips, menus, or dialogs.
• Localization audit is required for every user-facing change.
• defaultValue, English fallback text, schema descriptions, or copied English strings do not count as localization.
• For localized web/docs content, update every supported message catalog, currently web/messages/en.json and web/messages/ja.json, plus any localized data structures carrying inline translations.
