chore: ROADMAP Phase 8, parallel AI team script, docker and infra updates

- ROADMAP.md: add Phase 8 — Freifunk / Community Mesh Networking with
  F0-F8 checkboxes; F0-F2 marked complete
- scripts/ai_team.py: rewrite to support asyncio.gather parallel agent
  runs; add --sprint flag with predefined work packages (audit,
  phase1-hardening, phase2-tests, phase1-infra, status); add --parallel
  for ad-hoc concurrent agent invocations; output written to
  logs/ai_team/<sprint>_<timestamp>/<agent>.md
- scripts/dev-shell.sh: convenience development shell helper
- docker: update Dockerfiles for quicproquo rename and new server flags
- .gitignore: add qpq-state artifacts (*.bin, *.session, *.pending.ks,
  *.convdb*)
