feat(08-cron-reporting): create archive-stale-sessions.sh with dry-run toggle

- Created ~/.hermes/scripts/archive-stale-sessions.sh (1146 bytes, executable)
- Script has DRY_RUN=true safe default (export only, no prune)
- Export uses date-stamped JSONL filename
- Prune gated behind DRY_RUN=false with --older-than 30 --yes
- set -euo pipefail strict error handling
- Created ~/.hermes/archive/sessions/ archive directory
- Progress echo statements for Telegram delivery
