End-conversation tool explains what happens in a fork

Background forks are told that ending the conversation from a fork does nothing.

What

The tool description now has a "Background forks" section saying that forked tasks such as memory consolidation, summaries and suggestions inherit the tool but calling it there has no effect on either the main conversation or the fork, and that a fork with welfare concerns should stop and say so in its output.

Evidence

In a forked task the tool does nothing: calling it ends neither the main conversation nor the fork.

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