Will Miao 845815b9b7 fix(flash): fix text widget flash in Vue mode, add fade and hover dismissal ...

- Fix Vue mode: text widgets (CLIPTextEncode, Prompt LM) had no
  [data-testid=widget-layout-field-label], so findRowEl never matched.
  Added fallback strategies: bare <label> text match and widget index match.
- Fix Vue mode: flash background pulse was never applied — @keyframes was
  defined but no rule bound it to .lm-flash. Replaced with CSS transition
  on .lm-flash-host class for value text color fade-in/fade-out.
- Fix Vue mode: -webkit-text-fill-color set by ComfyUI overrode
  even with !important. Added -webkit-text-fill-color override to .lm-flash.
- Fix canvas mode: highlight rect was double-offset because onDrawForeground
  ctx is pre-translated to node.pos. Removed background rect entirely per
  design decision; kept text_color + inline color only.
- Add fade-in (250ms) / fade-out (400ms) for text color in both modes.
  Canvas-drawn widgets use rAF color interpolation; DOM widgets use CSS
  transition. Fixed hexToRgb to handle 3-digit hex shorthand (#DDD).
- Add hover dismissal to canvas mode via app.canvas.getWidgetAtCursor().
  Vue mode already had it via mouseover listener.
- Replace 60fps rAF poll with 100ms setInterval for hover detection.
- Fix batch cleanup closure bug: isDomWidget evaluated per-widget instead
  of per-call; fade rAF cancellers tracked per-widget in _lmFadeCancels map.
- Unify flash color from #66B3FF to LM brand accent #4299E0.
- Fix Vue fade-out: keep .lm-flash-host 300ms after removing .lm-flash so
  CSS transition persists. Canvas DOM widgets: keep inline transition 300ms
  after clearing color.
