hermes - 💡(How to fix) Fix [Feature]: Add Japanese language support (i18n / localization)

Problem or Use Case

Hermes Agent currently only supports English and Simplified Chinese in the UI and system messages.

For Japanese users, there are two major problems:

1. The entire interface is in English, making it difficult to understand.
2. When typing Japanese directly in the chat, the send function becomes unresponsive or blocked.

As a workaround, typing in Notepad first and then copy-pasting works, but this is very inconvenient for daily use.

Proposed Solution

Add official Japanese language support (i18n), including:

• Translation of UI strings and system messages into Japanese
• Proper handling of Japanese input so that direct typing does not block the send function

Alternatives Considered

Currently using manual translation by the AI for system messages, and using copy-paste from Notepad as a workaround for input issues. However, this is not a sustainable solution.
