Status bar shows Chinese text "致性检查" instead of English

Description
The status bar occasionally displays Chinese text "致性检查" (partial for 一致性检查,
"consistency check") instead of an English label.

Environment

• OS: Linux 6.6.135-09383-g1140e4f27e24
• Shell: bash
• TZ: America/Toronto
• LANG: en_US.UTF-8
• No locale/language/region keys set in ~/.claude/settings.json,

~/.claude.json, or ~/.claude/settings.local.json

What I expected
Status bar text in English, matching system locale (en_US.UTF-8).

What happened
Status bar briefly showed "致性检查" during a session — appears to be a
mislocalized or partially-translated internal task label, not tied to any
locale/timezone setting on my system (verified: TZ and LANG are both
correctly set to Canada/Eastern, no Chinese locale config anywhere).

Impact
Cosmetic — did not affect functionality, but is confusing since I have no
Chinese locale configured anywhere.
