feat: auto-suspend tasks on quota errors, add Claude progress tracking

- Auto-suspend tasks after 3 consecutive quota/auth errors with
  retry-after date parsing and Discord notification
- Add tool_progress and tool_use_summary streaming from Claude Agent SDK
- Prefix progress messages with invisible marker so bots ignore them
- Fix misleading provider label in codex service logs
