Buddy (Nachos) does not respect the `language` setting

Description

The /buddy companion always speaks in English, even when the language setting is configured to "japanese" in ~/.claude/settings.json.

Steps to Reproduce

1. Set "language": "japanese" in ~/.claude/settings.json
2. Start Claude Code — Claude's responses are correctly in Japanese
3. Run /buddy or /buddy pet
4. Observe that Nachos' speech bubbles and profile card are all in English

Expected Behavior

Nachos should speak in the language specified by the language setting (e.g., Japanese).

Actual Behavior

Nachos always speaks in English regardless of the language setting. Examples:

• /buddy pet → "petted Nachos" (expected: Japanese)
• Speech bubble: "Reboot didn't fix the language config. Classic." (English)
• Profile card description is in English

Additional Context

• The user reports that Nachos was speaking Japanese in a previous version, suggesting this is a regression.
• Claude Code version: 2.1.91+
• The language setting correctly affects Claude's main responses, just not the buddy feature.
