Support for summarising messages in a timeframe

[juschmitt]

It would be nice to be able to get a summary of messages that happened in a channel in a given timeframe.

A perfect usecase would be to get a quick summary of what happened while you were on vacation.

Usage could be like: "summarize messages from 03.01.2025 10am until 04.01.2025 8pm"

Another idea is to have a usage like: "summarize yesterdays messages" which would just be a shortcut for "summarize messages from 03.01.2025 0:01am until 03.01.2025 11:59pm"
