Simplifies the preset-chip picker (Smart Resize / Smart Batch Resize)
to a single canvas implementation - drops the dual DOM-widget path,
so chips stay positioned correctly under "Longest side (px)" in both
classic and Nodes 2.0 rendering instead of jumping to the bottom of
the node.
Adds a shared setWidgetVisible() helper so dynamic show/hide (Counter
start, the hidden customtext output on every node) actually works
under Nodes 2.0's Vue reactivity - it previously only worked in
classic canvas mode.
Fixes two silent Nodes 2.0 rendering bugs: widgets only repaint via
their own triggerDraw(), not setDirtyCanvas(), so the active preset
chip and status-box text were going visually stale after an update
even though the underlying value was correct. And Nodes 2.0's
WidgetLegacy bridge permanently stamps a widget.width that classic
mode's own click hit-test then reads forever after - once a node had
ever rendered under Nodes 2.0, classic mode silently lost clicks on
the right side of a wide node. Both fixed by keeping widget state in
sync on every draw() instead of trusting it to survive across
renderer switches.
Also centers section-divider labels with flanking lines (was
label-left/line-right) and brightens the line color, which had
become nearly invisible under Nodes 2.0's extra canvas scaling.
README: reorders node sections into actual pipeline order (Prompt
Controller -> Profile Switch -> Resize -> Resolution Multiplier ->
Batch Resize, standalone tool last instead of mid-list), adds a
Nodes 2.0 compatibility screenshot, and refreshes the Smart Batch
Resize screenshot to match its current UI.
