docs(agents): normalize gating terms and drop duplicate clauses

Use one wording per gating family: exact target and scope, recovery path or safety guard, and explicit authorization. Remove the home-directory instance from workspace access and the repeated approval gate from the breaking-change bullet. Sync the high-impact eval scenario wording.
