Subject: [PATCH] feat: add Copy, Paste, Select All commands to Edit menu
 (#8954)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

- Add Copy, Paste, and Select All commands to the Edit menu for
mobile/touch users and accessibility
- Menu-based copy uses LiteGraph internal clipboard; existing Ctrl+C/V
behavior is unchanged

## Changes

- `useCoreCommands.ts`: Register three new commands (`CopySelected`,
`PasteFromClipboard`, `SelectAll`)
- `coreMenuCommands.ts`: Add menu entries under Edit (between Undo/Redo
and Clear Workflow)
- `useCoreCommands.test.ts`: Add unit tests for the new commands

### TO BE

/>


## Test plan

- [x] Verify Copy/Paste/Select All appear in Edit menu
- [x] Select nodes → Edit > Copy → Edit > Paste → nodes duplicated
- [x] Edit > Select All → all canvas items selected
- [x] Copy with no selection → no-op (no error)
- [x] Existing Ctrl+C/V keyboard shortcuts still work

Fixes #2892
