- Introduced SSR‑safe ID generation using `$props.id()`.
- Fixed multiple bugs: derived state assignment respects private/public, correct value/checked handling with spread, template cloning for Firefox, and $derived ownership validation.
- Adjusted effect self‑invalidation logic and transition dispatches to run outside reactive context.
