-Fix Svelte readable-store subscriptions to deliver mutations synchronously,
-including mutations made by the initial callback. Prevent callbacks after
-unsubscription and clean up if the initial callback throws. Ordinary core
-subscriptions remain batched. Add regressions for Svelte 5 input editing,
-computed values, list updates, and component cleanup.
