Adds the visual feedback that was missing from the C10 resize + C2
selection commits. The canvas previously set the .selected class but
no CSS rule styled it, so a selected node looked identical to an
unselected one. Same for hover and the resize handle.
CSS additions (src/flowchart-generator.html):
- .flowchart-node: cursor:grab + 0.12s filter transition for the
hover tint (drop-shadow blue glow).
- .flowchart-node:hover .flowchart-node-shape: blue glow.
- .flowchart-node.selected .flowchart-node-shape: 2.25px blue
stroke — replaces the (previously invisible) .selected class.
- .flowchart-edge:hover and .flowchart-edge.selected: blue
stroke + 2.5px width for the same reason.
- .flowchart-resize-handle-hit: 24px transparent rect for an
enlarged hit area (the visible grip stays 10px).
- .flowchart-resize-handle-grip: blue square with stroke, styled
via CSS instead of inline fill/stroke (which were overriding
the rest of the file's theme).
- .flowchart-edge-label-bg: opaque white pill behind edge labels,
so labels stay readable when an edge curves under them.
- .fc-modal / .fc-modal-overlay: fade + scale-in keyframes
(0.15s ease-out) so the promptInline / confirmInline modals
animate in instead of popping in instantly.
Canvas (src/flowchart/flowchart-canvas.js): the resize handle now
emits two rects — a 24px transparent hit area (data-resize-node
attribute preserved) and a smaller 10px visible grip styled via
.flowchart-resize-handle-grip. Cursor stays nwse-resize via CSS.
Tests: no new tests (visual); existing 14 canvas tests still pass.
