Unclear What this changes for someone running a self-hosted runner is not clear.

What

The self-hosted runner is the program that runs Claude Code sessions on your own machines. It now starts a tool host for child processes of the kind tool-server. It also hands each child process information about its checkouts (copies of a code repository), when those checkouts started, and the session's folder.

Why

This is groundwork in the self-hosted runner for sessions that use tool servers.
