v1.25.1 — Maintenance

Maintenance

No gameplay changes — dependency updates and documentation fixes.

• FastAPI 0.141 and uvicorn 0.52 (from 0.139 / 0.51). Verified with the
  full test suite plus a complete game played over real websockets — lobby,
  host controls, all four rounds, the payoff gate and finish.
• Docs: the board screenshot now shows the lobby — the screen players
  actually see — rather than the idle screen.
• Docs: clearer guidance that guest networks often block guests from reaching
  any other host (client/AP isolation), not just the main LAN, and that the
  join URL must be reachable from the guest network.
• Docs: note that browsers need one click before the first round's audio will
  play.

Docker images for this release are published to GHCR and Docker Hub.
