Four polish features in one push.
1. Reduce-motion clamp. FaiEditorStyle.clampedForA11y(
disableAnimations: ...) returns a style with glass, gradient,
flow animation, and node shadows forced off when the OS
reduce-motion preference is set. FlowCanvas + FlowEditorPage
call it on every build with
MediaQuery.disableAnimationsOf(context) so operators on
accessibility settings get a flat, static editor without an
explicit Studio setting.
2. Edge gradient source→target. EdgePainter now accepts an
optional colorEnd per segment and paints a linear shader
along the bezier when both ends carry distinct type accents.
In practice this draws attention to type mismatches: a
text→json wire reads as a colour transition; a same-type
wire stays a solid colour. ModuleSpec lookup at both edge
endpoints feeds the colour pair.
3. Breathing pulse on running steps. FlowNode accepts a
Listenable pulse; when status=running AND the canvas's
_flowAnim is ticking, the node wraps in an AnimatedBuilder
that drives a sine-wave shadow halo (alpha + blur + spread
oscillating). Stops when the run completes. Gated by
_style.flowAnimation so reduce-motion / minimal-style modes
stay still.
4. In-editor style sheet. Bottom-right canvas chrome gains a
⚙ Style button that opens a modal bottom sheet with four
SwitchListTiles (glass, gradient backdrop, flow animation,
node shadows) plus 'Reset to default'. Edits live in
_styleOverride on the canvas state — operator can tweak the
look for the session without restarting or editing code.
No persistence in this version; follow-up could pipe the
override through SharedPreferences via the host.
Bumps fai_studio_flow_editor to 0.10.0.
