Claude Code: Fix health check - use dynamic path for status file, return 'idle' instead of 'unknown'

- Change hardcoded /app path to dynamic based on working directory
- Return 'idle' (healthy) instead of 'unknown' (treated as error) when status file not found
- Add status_file path to response for debugging
