OptionalexecutionExecution environment — propagates to subflows automatically.
OptionalreadOptionalresumeThe resume's one-shot re-entry (M2) — shared by reference with every
nested traverser, like the execution counter. SubflowExecutor asks it
at each subflow entry: the FIRST entry into a subflow on the pause path
takes that subflow's captured state (seeding the nested runtime in place
of the inputMapper's values — the mapper still runs for the read-only
args), its entry point and any sibling pauses waiting there; every later
entry is an ordinary one. See ResumeEntry. Undefined on normal run()
paths.

HandlerDeps — Dependency injection bag passed to all handler modules.
Provides shared state (stageMap, runtime, scopeFactory, etc.) without handlers needing to import the traverser directly. Avoids circular deps.
