"""Complete unit tests for plugin/hooks/workflow_reminder.py.

Coverage targets:
- _check_agent_team_name: team_name enforcement, readonly bypass, non-Agent pass
- _check_leader_doing_too_much: consecutive call counter, delegation reset
- _check_team_has_permanent_members: every-20-call scan, QA+bug-fixer detection
- _check_workflow_reminders: all 14 rules + 3 safety rule groups (S1/S2/S3)

Test philosophy: guilty-until-proven-innocent. Every rule has at least one
positive trigger test and one negative (non-trigger) test. State mutation is
verified explicitly after each call.
