Feature Request: Localization support for Knurl companion (speech bubble language)

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

The Knurl snail companion's speech bubbles are displayed in English only, with no configuration option to change the
language. For non-English users, this creates a disconnect — the entire workflow is in their native language, but the
companion speaks only English. There is currently no setting in settings.json or elsewhere to control this behavior.

Proposed Solution

Add a locale setting for the Knurl companion, either in settings.json or as a Claude Code configuration option.

Example:
{
"buddyLocale": "ja"
}

This would allow the speech bubble messages to be displayed in the user's preferred language, consistent with the rest
of their localized workflow.

Alternative Solutions

No viable workaround currently exists. The companion's messages are hardcoded in English and cannot be suppressed or
redirected. We have submitted feedback through this issue as the only available channel.

Use Case Example

1. User works entirely in Japanese — prompts, responses, file comments are all in Japanese.
2. Knurl appears and displays an English speech bubble.
3. The language switch breaks the immersion and is mildly confusing.
4. With a "buddyLocale": "ja" setting, Knurl would display messages in Japanese, keeping the experience consistent.
