v2.15.4

This release focuses on distributed worker stability, shared-nothing execution isolation, and memory bounding across the event pipeline. Distributed workers now properly clean up workspace bundles and release coordinator resources on completion, alongside extended lease grace periods to prevent false expiration under transient coordinator load.
