Remember Slack Users Across Threads
===================================
Resolve a Slack member to an email-backed user ID when available, then use a
MemoryManager to retain stable preferences across otherwise separate threads.
Prerequisites: SLACK_TOKEN, SLACK_SIGNING_SECRET, OPENAI_API_KEY
Run: .venvs/demo/bin/python cookbook/05_agent_os/17_slack/user_memory.py
Try in Slack: Share a preference in one thread, then ask about it in a new thread
Slack scopes: app_mentions:read, assistant:write, chat:write, im:history, users:read, users:read.email
