Add missing <returns>/<param>/<summary>/<typeparam> tags and clean up misused inheritdoc across 481 files so the documented API surface is complete. Documentation-only (zero code lines changed). The 131 remaining findings are inheritdoc-style warnings deliberately left to preserve hand-written implementation rationale (plan-decision notes, race-condition explanations).
