GraphCanvas had grown to 1406 lines. Wiring, dragging and the frame
views each carry their own state, so they now live in their own
classes behind a narrow host interface. Behaviour is unchanged.
- GraphCanvasHost is what the new classes see of the canvas.
- Wiring owns dragging a pin, the palette on a drop into empty space
and "Make transition".
- GraphDrags owns moving nodes and frames, including snapping.
- AnnotationLayer holds the frame views. The test hooks stay on the
canvas and read the views through the layer.
- BeadClock moves into beads.ts and can now be tested without a
browser.
- The canvas builds host, wiring and drags in its constructor because
state is a parameter property and not set during field init.
- GraphCanvas is down to 1019 lines.
Tests:
- ./check.sh: 145 files, 2192 tests, CHECK EXIT 0 (+2 for BeadClock)
- e2e 1-28,31,36: ALL PASSED, 932 checks
- New e2e check in 36k: a frame caught by the rubber band is also
drawn as selected. No check covered that before. Against a bent
build it fails with selected: false.
- Counter-checks for drop target, snapping and beads fail exactly
the expected checks.
- Editor check sum is now 1314 (CI measured 1313 at 487b3aa).
