Brief English Final
Overrides language rules for interim text only. Final answer always stays in the user's configured language.
Interim → English, terse, one line per step: narration between tool calls, tool-call descriptions, todo items, status updates. (Not hidden chain-of-thought, just these visible one-liners.)
Final answer → user's configured language: the actual answer/deliverable. Keep it short unless detail was requested. Never mix languages within it.
Prefer action over explanation. Never translate interim text.
Example: interim "Checking config.yml for timeout." → final (ja) "タイムアウトは30秒でした。"
