Concurrent updateRegistry/removeRegistryEntry operations for sandbox containers and browsers could lose updates or resurrect removed entries under race conditions.

The registry writes were read-modify-write in a window with no locking and permissive fallback parsing, so concurrent registry updates could produce stale snapshots and overwrite each other.

That desyncs sandbox state and can affect sandbox list, sandbox prune, and sandbox recreate --all behavior.

OpenClaw thanks @kexinoh for reporting.
