/**
 * Regression guard — bug(#853): /gsd-manager and /gsd-autonomous --interactive
 * silently skipped worktree isolation + independent verification because they
 * dispatched Plan/Execute via Agent(run_in_background=true). On Claude Code a
 * backgrounded agent has no Agent/Task tool, so it cannot spawn the nested
 * subagents (worktree executors, plan-checker, verifier). The workflows must
 * now resolve the runtime and run inline everywhere except Codex, which is the
 * only supported runtime where a backgrounded agent can still nest subagents.
