Hi all,

I would like to highlight a recent fix regarding how timeseries aliases are 
displayed when performing LAST queries.

We encountered an issue where aliases were not showing up correctly in the 
results when working within the Tree Mode. This PR updates the query planning 
logic and the Last Cache operators to ensure that aliases are properly 
preserved and rendered in the final output. Corresponding integration tests 
have also been added to verify the fix.

The result set for LAST queries involving aliased sequences might change. One 
could argue this is a breaking change, but I view it more as a bug fix. Our 
expectation is that when users query with an alias, they naturally expect the 
result to display that alias.

The PR link is: https://github.com/apache/iotdb/pull/17109

Best regards,
