Topic Tracker

Compile a daily digest of developments on tracked topics:

1. Recall — Read memory for tracked topics and previous findings
2. Search — For each topic, search for news/developments from the last 24 hours
3. Filter — Skip articles already in memory, focus on genuinely new information
4. Build canvas — Create or update a digest dashboard:
   • Date badge at top
   • Card per topic with latest headlines and summaries
   • Table of all new articles with source, date, and summary
5. Persist — Save the digest to memory with today’s date
6. Notify — If a channel is configured, send a summary via send_message

If no topics are configured yet, ask the user what they want to track and save to memory.
