feat(statechart): Phase 5 — ufo-types DecisionNode/ForkNode/JoinNode extension for process chart completion #268
Description
Context
Spin-off from #259 (closed). Phases 1–4c of the statechart unification are done. Phase 5 depends on ufo-types gaining Rust type definitions for DecisionNode, ForkNode, and JoinNode.
Blocker
ufo-types PR #13 (PromptExecution/ufo-types) must merge first. Current pin: rev = "5f8d018" — has ElementKind::ActionUsage, ActionDefinition, Relation::Succession but no control-flow node types.
