Closes the gap left by #467: a room member at no go table never heard a game end, so the Go games section never appeared for them until they rejoined.

• LobbyGame asks for go history again whenever the room's go tables, or their statuses, change. Every member hears that room state, seated or not. MoonBase#1687 pins the hub side.
• Arrival asks once, and keeps asking on each room state until an answer lands. That covers a game ending mid-ask and a failed ask.
• This replaces the gameEnded re-ask in useGoTable and Go: the room's finished games, each with its SGF #467's "keep the section up while there's a go table". The section shows only once the room has played go.

The new tests failed first. A mutation that double-asks on arrival is killed. Typecheck, lint and all tests pass. The review ran as 2 agents covering the 4 lenses (correctness; tests, simplicity and UX); its follow-ups are in 4a0251b.

Review

Altitude looks right: this is the proper fix for the #467 bystander gap. Room-state go table fingerprint (gameId:status) is what every member hears; gameEnded re-ask and the “keep the section up while a go table exists” workaround go away; section shows only once history is non-empty. Arrival asks while history === null (and retries on room churn until an answer lands); later asks are gated on the fingerprint so chess-only room noise does not re-hit history. Matches MoonBase#1687. CI green.

Low — no pin that non-go room churn stays quiet after history lands

The LobbyGame tests cover go status changes, arrival-once, change-before-answer, and room switch. Nothing asserts that with go.history = [] already held, a room update that only adds a chess table (same go fingerprint) does not call loadGoHistory. That is the mutation the fingerprint exists to kill.

Ack on 731ffef: the “only other games change” pin is exactly the fingerprint mutation.
