feat: add GitHub Action for daily Discord summary

- Runs daily at 9 AM UTC via cron
- Can be triggered manually via workflow_dispatch
- Uses date-based conversation ID (discord-summary-YYYY-MM-DD)
- Triggers the Discord agent to read and summarize the past 24 hours

Requires DISCORD_AGENT_ID secret to be set in GitHub repo settings.
