Step run events were previously visible only on the run tab.
Operators who triggered a run there and then switched to
the graph tab saw a static graph — the canvas had no idea
something was executing.
Wire the run events through the FlowEditorController so all
three tabs share the same status snapshot:
- New StepRunStatus enum on the controller
(idle / running / done / failed / awaiting).
- controller.stepStatuses exposes the live map.
- controller.updateStepStatus is called from the run tab's
event handler — one source of truth, both views read it.
- FlowCanvas drops its own stepStatuses parameter and
pulls from the controller instead, so the canvas now
shows the running pulse + done check + error cross + pause
icon in each step's header live, in lockstep with the
step list on the run tab.
When a fresh run starts (controller.running = true) the
status map is cleared so stale events from a previous run
don't paint the new one.

Full rewrite of the editor surface, layered on top of the
FlowGraph foundation. One in-memory flow drives three tabs
that the operator can flip between freely:
- Graph: a drag-and-drop canvas. Nodes are step cards with
port dots on their left (one per `with:` field) and a
combined output port on the right. Pinned inputs and
outputs pseudo-nodes sit at the left and right edges so
every flow has a visually obvious source and sink. Pan +
zoom via InteractiveViewer; drag a node by its body to
reposition it (positions persisted to a sidecar JSON file
under ~/.fai/data/flows/.layout/<name>.json — kept OUT of
the YAML so `fai run` stays byte-stable).
- Text: the existing YAML CodeField with expands:true so
line 1 anchors at the top edge. YAML-aware syntax
highlighting picks up the theme's primary / secondary /
tertiary palette for keys / strings / numbers.
- Run: an inputs form (text fields + file-pick), a Start
button that calls the host's FlowRunDriver, a live step
list driven by the driver's event stream (matches the
`fai run` CLI rendering — ◻ pending, · running, ✔ done +
duration, ✗ failed, ⏸ awaiting approval), and the typed
outputs once the run resolves.
Source of truth = the YAML text. Graph edits emit fresh YAML
into the shared CodeController; text edits re-parse the
graph on a 350 ms debounce. Layout sidecar persists drag
positions only.
New public API (lib/fai_studio_flow_editor.dart):
FlowEditorPage(
initialFlowName: ...,
locale: ...,
runDriver: FlowRunDriver?, // NEW — host bridge
availableCapabilities: List<String>, // NEW — for the
// capability picker
// dialog when adding
// a step
)
The host (Studio) implements FlowRunDriver to bridge the
hub's gRPC SDK into the editor's event vocabulary. The
StepStarted/Completed/Failed/AwaitingApproval events are
shared verbatim with the CLI's run_progress renderer so
both surfaces speak the same visual language.
