create_tool_instance fetched `project` only inside the auto-display-name
branch, so callers supplying display_name left it unbound and the
manifest/dockerfile/compose branches crashed with UnboundLocalError at
_get_repository_mount_name (in-container layout /home/user/{project_name}).
Resolve project unconditionally after repo validation with a not-found
guard (narrowing Project|None -> Project), and drop the now-redundant
fetch from the auto-name branch. Add a regression test covering the
manifest + display_name path.
