NewLogr returns a logr.Logger which writes to the slog.Handler.

NewSlogHandler returns a slog.Handler which writes to the same sink as the logr.Logger.

ToSlogHandler returns a slog.Handler which writes to the same sink as the logr.Logger.

SlogSink is an optional interface that a LogSink can implement to support logging through the slog.Logger or slog.Handler APIs better.
