fix: dedup intermediate/final, filter long descriptions, update SDKs

- Track lastIntermediateText to prevent duplicate Discord delivery
  when same text arrives as both intermediate and final
- Filter task_progress descriptions >80 chars (AI summaries)
- Mark completed subagents with ✅ instead of removing
- Update claude-agent-sdk 0.2.76→0.2.81, codex 0.115→0.116
