Activity Monitor shows garbled process name on macOS (Japanese locale)

On macOS with Japanese locale, the Activity Monitor displays a garbled process name like "莉ョ諠ウ繝槭す繝ウ繧オ繝シ繝薙せ" (likely "推論マシンサービス" with broken encoding) instead of a readable name like "Claude Code".

Environment

• macOS (Darwin 25.2.0)
• Japanese locale

Expected

Process name should display as "Claude Code" or at least be properly encoded.

Actual

Process name appears as mojibake (文字化け) in Activity Monitor.
