fix: resolve extraneous attrs warning in TreeExplorerV2Node (#9735)

## Summary

Fix Vue warning about extraneous non-props attributes (`data-index`,
`style`) in `TreeExplorerV2Node`, which caused the Node Library sidebar
to freeze.

## Changes

- **What**: Added `defineOptions({ inheritAttrs: false })` and
`v-bind="$attrs"` on both node/folder `<div>` elements so the
virtualizer's positioning attributes are properly applied to the
rendered DOM.

## Review Focus

`TreeExplorerV2Node` has a fragment root (`<TreeItem as-child>` +
`<Teleport>`), so Vue cannot auto-inherit attrs. The virtualizer's
`style` (positioning) merges cleanly with `rowStyle` (`paddingLeft`
only).
