The standard email footer told dispatched agents 'CLOSE FPLAN -> drone @flow
close <plan_id>', which led them to close the orchestrator's master/parent plan
referenced in their brief (bit us in FPLAN-0260). Reworded to 'CLOSE YOUR PLAN
-> ... this task's plan only, never the master/parent': a worker still closes the
sub-plan handed to it, the master stays the orchestrator's to close on completion.
td-6. Footer string + test assertion; 737 ai_mail tests pass.
