Check thread closer use-case

Use Case: Slack Thread Bump/Reminder

Concept:
Every X time, scan all ongoing threads and:

• If the conversation did not reach a conclusion AND
• More than X time passed since the last message

Actions:

1. Send a message in the thread to "bump" it
2. OR (better): Send a DM to the person who needs to respond next to remind them of the thread

Notes

• Need to determine how to detect "conversation didn't reach conclusion"
• Need to identify "who needs to respond next"
• Configurable time threshold (X)
