+Make CLI bridge turns resumable, idempotent, and cancellation-safe using server-owned run state, and derive bridge selection from run data.

+The bridge model is selected from run data in this order: the turn, the provider default, or the profile's `harness` plus `model.default`.
+Execution fails before network use when none is present.
+
+Passing the same `sessionId` on later turns continues the same CLI conversation.
+`executionId` gives a turn stable bridge identity, and `lastEventId` reattaches after a reader failure.
+Stopping a reader or destroying the environment cancels every active bridge run and waits for terminal confirmation.
+
 Response headers and streamed bodies have no transport timeout by default.
 For unattended runs, set `headersTimeoutMs`, `bodyTimeoutMs`, or an `AbortSignal` so an unresponsive bridge cannot wait forever.
