Subagents now announce when they finish, fail or are killed, and nothing listens yet.

Settled, spawned and resume-failed subagent events are published with no subscriber in this build.

What

Subagent completion, failure and kill now publish a settled event carrying the outcome ("completed" with a stranded-messages flag, "failed", or "killed"). Nothing in this build subscribes to it, nor to the spawned and resume-failed events; the only subagent channel with a listener is the stranded-messages one. This is groundwork with no visible effect yet.

Evidence

agentSettled

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
