Problem
The human ↔ planner revision loop in
_add_workflow_edges()had noexplicit upper bound on revisions. A runaway "revise" feedback loop
would silently hit LangGraph's default recursion_limit=25, causing a
confusing GraphRecursionError with no clear signal.
Fix
Added a MAX_REVISIONS = 5 guard with a force_accept branch that
redirects to researcher after 5 revisions, preventing infinite loops.
