Extract shared pressInputKey test helper.

This helper is duplicated near-identically in EditorFileTab.test.tsx (lines 331-351) and SortableTab.rename-shortcut.test.tsx (lines 289-307, minus stopPropagation), and re-implemented with a different (real DOM KeyboardEvent) approach in TerminalPaneHeaderOverlay.test.tsx (lines 103-127). The copies have already diverged (some return stopPropagation, some don't), which risks further drift in this IME-composition-critical test coverage. Consider moving this into a shared test utility (e.g., a press-input-key helper module) reused by all four files.

♻️ Example extraction

// src/renderer/src/lib/test-utils/press-input-key.ts
export function pressInputKey(
  input: ReactElementLike,
  key: string,
  options?: { isComposing?: boolean; keyCode?: number }
): {
  preventDefault: ReturnType<typeof vi.fn>
  stopPropagation: ReturnType<typeof vi.fn>
} {
  const event = {
    key,
    nativeEvent: {
      isComposing: options?.isComposing ?? false,
      keyCode: options?.keyCode ?? 13
    },
    preventDefault: vi.fn(),
    stopPropagation: vi.fn()
  }
  ;(input.props.onKeyDown as (nextEvent: typeof event) => void)(event)
  return event
}

Duplicated pressInputKey helper across test files.

This helper is duplicated verbatim (same signature, same event shape) in SortableTab.rename-shortcut.test.tsx and WorktreeTitleInlineRename.begin-editing.test.tsx. Consider extracting a shared test utility (e.g. src/renderer/src/lib/test-utils/press-input-key.ts) that all three consume, reducing drift risk if the IME contract changes again.
