What
This build adds presentAdoptedHostTools and a new provisional_host_tools field on the tengu_remote_tool_restart_adoption event. Both handle tool calls that were still running when a worker restarted in headless print mode.
Whether those calls are adopted depends on an internal switch, and in this build that switch always returns false. The list of calls to adopt is therefore always empty, and the new presentation path receives nothing. The same switch empties the restore list when a session is resumed.
Why
In this build, after a restart, in-flight calls are not picked back up through this path.
