コントラクト

• zap.NewAtomicLevelAt enables dynamic log level switching at runtime so that calling SetLevel immediately enables debug log emission across base, child, and sugared loggers without reconstructing the core.
• logger.Core().Enabled(zapcore.DebugLevel) transitions from false to true immediately following atomicLevel.SetLevel(zapcore.DebugLevel)
• derived child loggers created via With and SugaredLogger instances share the same AtomicLevel reference and reflect level mutations immediately
• atomicLevel.UnmarshalText updates the filtering threshold dynamically to warn level, suppressing info logs
