Persist the paused-for-wake state across adapter sessions.

goalsPausedForWake lives only in one Codex adapter session. The session manager can release an idle session while a delegated task is still pending. The idle probe does not count an open delegated completion. After the release, the wake starts its turn on a new adapter with an empty set. The startTurn check at line 7689 then skips activateGoal, and the goal stays paused. A server restart clears the set in the same way.

Store the paused-for-wake state outside the adapter session, or rebuild it from durable state. The activation check also requires the goal status to read "paused" from goalsByNativeThread. A new adapter does not read the goal state on this path, so the fix must cover that status as well.

Review comment at @apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.ts at line 2049:
Persist or rebuild the paused-for-wake state used by `goalsPausedForWake` so it survives adapter release and server restart. Ensure a new adapter also loads the goal’s paused status into `goalsByNativeThread` before the `startTurn` check can skip `activateGoal`; use the existing durable state mechanism and preserve the activation behavior for paused goals.

Keep the wake marker until the goal activation succeeds.

activateGoal clears goalsPausedForWake before it starts the wake turn. If startNativeTurn or thread/goal/set then fails, the marker is gone. The goal stays paused, and the next ordinary turn does not reactivate it. The goal stops until the user sends a /goal command.

Clear the marker only after activation succeeds. Clear it also when Stop cancels activation, so a stopped goal is not reactivated later. A failed activation then keeps the marker for the next ordinary turn.

Suggested fix 

-          goalsPausedForWake.delete(threadId);
           // Hold fast first turns until activation.
           const activation = { stopped: false };
           goalActivations.set(threadId, activation);
           yield* Effect.gen(function* () {
             yield* startNativeTurn(turnInput, yield* codexInput);

Review comment at @apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.ts at line 7284:
In the `activateGoal` flow, keep `goalsPausedForWake` set while activation is in progress so failures in `startNativeTurn` or `thread/goal/set` leave the goal eligible for reactivation on the next ordinary turn. Delete the marker only after `thread/goal/set` succeeds, and also delete it when `activation.stopped` indicates Stop canceled activation.
