// writeWorkspacesRootMarkerAtomic writes data to path via a same-directory temp
// file plus a rename, so a concurrent reader observes either the old file or the
// complete new one — never a partial write. Mirrors the daemon-id / CLI-config
// write idiom (see writeDaemonIDFile). Perm is 0644 because the CLI's upward
// walk must be able to read the marker from a subprocess that may run under a
// different uid; the payload is non-secret.
