Time-Based Profile Summary

Enable users to request summaries of profile posts for specific timeframes using the syntax:

@FomoRadioAi <@username> [timespan=1d]
Available timespan options: 30m, 1h, 4h, 12h, 1d, 7d, 30d, ...

Currently, Radio can summarize individual posts and threads, but profile-wide summaries for specific time periods are not available. This feature would serve two key purposes:

1. Help users catch up on missed content from accounts they follow

2. Provide quick overviews of new creators' content for discovery purposes

The feature would enhance user experience by enabling efficient content consumption and creator evaluation through customizable time-based summaries. Additionally, since creators receive notifications when mentioned, this feature will naturally expand community engagement and awareness of the summarization service.
