Only delete the VM workdir during cleanup if the .removing marker file is present (set by user-initiated remove_vm). Orphaned supervisor processes discovered at startup without the marker now have their workdir preserved, preventing accidental data loss on VMM restart.

Summary
.removingmarker is present (user-initiatedremove_vm)Context
When VMM is killed and restarted, it discovers supervisor processes that don't match any loaded VM as "orphans" and calls
finish_remove_vmto clean them up. Previously this unconditionally deleted the workdir, destroying VM data (compose files, disk images, logs) that could be recovered.Test plan
remove_vmAPI — VM workdir should be deleted (.removingmarker present)remove_vmwith.removingmarker — cleanup resumes and deletes workdir
