Introduce the `true for` syntax to allow users to specify the minimum
duration for event and state windows. Add corresponding tests to
validate the feature. Updated the user manual with usage instructions.
Add the AUTO keyword, which allows automatic determination of the
INTERVAL OFFSET based on the WHERE condition. It simplifies usage by
allowing users to rely on the system to infer the correct offset
without manual specification.
