Agent-level stream event labels and emit helpers.

A thin wrapper over ::hot::stream (the engine-level emission primitive). This namespace defines the stable agent-level event labels (<agent>:reply:start / :delta / :end, <agent>:memory:forget:start / :end, …) and the helpers that emit them via ::hot::stream/data underneath.

Concrete agents and the harness's own chat-turn reach for these helpers so that custom UIs can subscribe to a stable, agent-scoped event surface while provider-level streaming changes underneath.
