Add editor / tool UX improvements to TODO

On-canvas resize handles for all layer types, a constraint that text-box
resize never rescales the point size, and expanding the existing
#textToolOptions panel like the pen-tool panel.

+## Editor / tool UX
+
+Small editor-usability improvements — no spec doc; scoped here.
+
+- **On-canvas resize handles.** Add draggable nodes on a selected layer's
+  edges and corners (text / shape / image / all layer types) so the user
+  can resize by dragging instead of typing into the W/H inputs. Corner
+  handles resize both axes (respecting the existing aspect-ratio lock
+  toggle); edge handles resize one axis. The handles live on the
+  `.freeLayer.selected` element and write back to the layer's `w` / `h`
+  (and `x` / `y` for top/left drags).
+- **Text box resize must not rescale the text.** Resizing a `text`
+  layer's box changes only the area the text flows within — `fontSize`
+  (points) stays fixed. (Distinct from image/shape, where the content
+  scales with the box.)
+- **Expand the Text tool panel.** `#textToolOptions` already exists but
+  is minimal (color + size). Build it out like `#penToolOptions` —
+  point size, font family, paragraph alignment, bold/italic — so text
+  styling is editable from the tool-options panel, not just the layer
+  panel.
