What
Claude Code keeps a per-session channel that announces which tools are available to a "worker" process. For channels marked control-only, the channel now notices when the worker disappears, and when it comes back online (onWorkerLive), it triggers a reconnected reannounce of the available tools. This is on top of the existing reannounce that already happened when the connection stream itself reconnected.
Why
Without this, a control-only channel whose worker dropped and came back could end up with a stale or missing record of which tools were available. Reannouncing on worker reconnect keeps that list accurate.
