Merge fix/textgate-prompt-weighting: prompt weighting in text gate editor

ComfyUI's "edit attention" (wrap selection in (token:weight)) is a global
window keydown listener that acts when a <textarea> is focused. The text
gate editor is a textarea, but its keydown handler called stopPropagation
on EVERY key, so the event never bubbled to window and weighting never
fired — notably when using the node as a prompt text node in protected mode.

Now stopPropagation is skipped for the weighting shortcut (Ctrl/Cmd + ↑/↓)
so it reaches the global handler; all other keys are still stopped so
typing/space can't trigger litegraph canvas shortcuts. The weighting edit
goes through execCommand, which fires our oninput -> stored_text stays synced.

Verified against the verbatim editAttention from the shipped frontend:
whole-word weighting, existing-weight decrement, and no-selection word
expansion all round-trip; plain keys stay stopped.
