Address confirmed code-review findings on the CE workflow-step change:
- Graph-path spawn lifecycle (adversarial A-1/A-2): the graph path returns from
execute() before its outer finally that calls terminateAllChildren, so U8's new
coding-mode fn_spawn_agent children orphaned their sessions/worktrees and their
ids accumulated in the per-parent spawn budget, starving later steps' fan-out.
Call terminateAllChildren in maybeExecuteWorkflowGraph's finally (mirrors the
non-graph cleanup).
- INVERSION CONTRACT parity (api-contract AC-2 + testing TF-001): add skillName to
the workflow-steps-to-ir round-trip projections + a skill-step fixture, so the
contract the comment claims is actually asserted.
- Silent skill-load degradation (adversarial A-3 / Risk-4): warn when a step names
a skill but FUSION_CE_SKILLS_DIR is unset, instead of failing silent.
- Dead branch (maintainability M-01): drop the always-false unattendedRun guard;
keep the delete + extension-point comment.
