Introduce a `metadata` method on SessionProcessor.Handle that buffers
metadata emitted before tool-call registration, then applies it on the
running transition. This decouples metadata emission timing from
tool-call lifecycle.
Downgrade virtua from 0.49.1 to 0.42.3 and migrate the virtualizer API:
- Replace `findItemIndex(scrollOffset)` with `findStartIndex()`
- Replace `bufferSize` prop with `overscan` (count-based)
Additional changes:
- Change Permission.reply return type from Promise<boolean> to Promise<void>
- Make Ruleset type readonly and remove unnecessary array spreads
- Update nvidia provider headers to reference Kilo branding
- Reorder SDK event type definitions for installation events
- Reduce promise facade allowlist in check script
