fix: address small CodeRabbit issues (#9229)

## Summary

Address several small CodeRabbit-filed issues: clipboard simplification,
queue getter cleanup, pointer handling, and test parameterization.

## Changes

- **What**:
- Simplify `useCopyToClipboard` by using VueUse's built-in `legacy` mode
instead of a manual `document.execCommand` fallback
- Remove `queueIndex` getter alias from `TaskItemImpl`, replace all
usages with `job.priority`
- Add `pointercancel` event handling and try-catch around
`releasePointerCapture` in `useNodeResize` to prevent stuck resize state
- Parameterize repetitive `getNodeProvider` tests in
`modelToNodeStore.test.ts` using `it.each()`

- Fixes #9024
- Fixes #7955
- Fixes #7323
- Fixes #8703

## Review Focus

- `useCopyToClipboard`: VueUse's `legacy: true` enables the
`execCommand` fallback internally — verify browser compat is acceptable
- `useNodeResize`: cleanup logic extracted into shared function used by
both `pointerup` and `pointercancel`
