feat: Add string resources for Create Agent V2

This commit introduces new string resources for the "Create Agent V2" feature.
These strings are provided in English, Chinese, and Japanese to support localization.

The added strings cover various UI elements and messages within the Create Agent V2 flow, including:
- Titles and labels (e.g., "Create AI", "Name", "Description")
- User guidance and prompts (e.g., "Hello %s! What would you like to create today?", "An AI that writes poetry...")
- Action button texts (e.g., "AI Enhancement", "Manually Create AI", "Alright, that's the one")
- Status messages (e.g., "Generating...", "Creating...", "Thinking for you")
- Accessibility descriptions for icons (e.g., "AI Avatar", "Edit Icon")
