docs(6205): task_logs, task_claims, reply_shapes, design_starter_roles, db_maintenance_scheduler comments drop citations and incident stories

- db_maintenance_scheduler states the storage-stall hazard the startup
  timeout guards, without the dated outage.
- design_starter_roles states why a missing role produces literals, without
  the call-site count, the operator's call date or a project's name.
- The rest drop milestone/step labels and record citations.
