Quick Task 16: Add Ctrl+A Hotkey to Multi-Select Views

SelectionController.selectAll() method with shortcut:select-all CustomEvent broadcast to track-list, queue-panel, and playlist-view

What Changed

Task 1: Add selectAll() to SelectionController and change app.selectAll dispatch

Commit: f567762

• Added selectAll() method to SelectionController that iterates all host items via getItemCount()/getItemKey() and builds a complete selection set
• Includes early-return guard when all items are already selected (prevents redundant updates)
• Sets lastSelectedIndex to the last item for consistent shift-click behavior after select-all
• Changed app.selectAll dispatch from document.execCommand('selectAll') (browser text selection) to document.dispatchEvent(new CustomEvent('shortcut:select-all')) following the existing shortcut event pattern

Task 2: Wire select-all event listener in track-list, queue-panel, and playlist-view

Commit: 906ea28

• Added handleSelectAll arrow method to all three components calling this.selection.selectAll()
• Registered shortcut:select-all event listener in connectedCallback() and cleaned up in disconnectedCallback() for all three components
• All three components may respond simultaneously but this is harmless — empty/inactive panels have 0 items and the selectAll early-return guard triggers immediately

Deviations from Plan

None — plan executed exactly as written.
