claude-code: undo a home removal through the mesh

A removal kept its copy but nothing could put it back without a shell on
the machine. claude_code_home_restore puts a kept copy back when nothing is
at its path and the copy matches the digests recorded at removal;
claude_code_home_removed lists what is kept.
