The flow editor is a Ch∆In Studio sub-component (chain product), not a F∆I-vendor package. Rename the package, entry library file, and all package: imports. flutter analyze: clean. Signed-off-by: flemming-it <sf@flemming.it>

// Behaviour tests for FlowEditorController — the bridge
|
|
// between the YAML buffer + the graph + the layout sidecar.
|
|
// The model tests cover parsing correctness; these cover
|
|
// that the controller wires text -> graph reparsing,
|
|
// graph -> YAML emission, selection bookkeeping, and
|
|
// dirty/saved transitions correctly.
