Expands README to describe the three-tab UX, the source-of-
truth model (YAML + sidecar layout), the FlowRunDriver
contract, the folder layout, and how to swap the editor.
Version 0.2.0 -> 0.2.1 — picks up the live step status,
the empty-graph CTA, and the fit-to-screen button added
since the initial 0.2.0 commit.

Extracted from fai/studio's lib/pages/flow_editor.dart so the
editor can be swapped out independently of the host.
Public surface kept minimal — a single FlowEditorPage widget
with three named parameters (initialFlowName, locale, onRun).
The package brings its own design tokens, empty/error
widgets, l10n table; no host-internal types leak through.
Studio depends on this repo via pubspec.yaml git reference.
Forks point Studio at a different URL and rebuild.
See README.md for the swap recipe.
