The twap() page said the timestamp argument could be any timestamp column. twap() now rejects anything other than the table's designated timestamp, because it relies on its observations already being in ascending designated-timestamp order. Update the parameter description to state this, framed as a current limitation. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

I would refrain from saying as a current limitation. We can just say it rejects a query that passes any other timestamp column. We can add a link to https://questdb.com/docs/query/functions/timestamp/ if the user needs to see how to convert a non-designated timestamp column into the designated timestamp for the query

twap()now rejects any timestamp argument other than the table'sdesignated timestamp. This updates the
twap()reference page so thetimestampparameter description states that requirement, framed as acurrent limitation.
Companion to the questdb engine change that adds the rejection.
