Remove the dead 'delete' member from the validation-rule events enum (#3184). The rule evaluator only runs on the insert/update write path — engine.delete never invokes it — so a rule declaring events: ['delete'] was a silent no-op (flagged in #3106 and docs/audits/2026-06-validationschema-property-liveness.md). The enum now admits only insert/update; guard deletions with a beforeDelete lifecycle hook instead. No shipped metadata declares events: ['delete']; any off-spec metadata that did now fails loudly at os validate / registration rather than parsing and doing nothing. Also narrows the two hand-written mirrors (rule-validator.ts BaseRule, metadata-protocol JSON-schema form helper — whose stale type enum listing removed unique/async/custom variants is corrected in the same pass), updates the doc comments, the published data skill, and the hand-written validation doc.
