feat(run): kernel-native result_schema — validate + in-loop self-repair

tool.Invocation.ResultSchema (JSON Schema, draft 2020-12): the executor validates the single-loop final answer and, on violation, runs up to two bounded corrective rounds on the same conversation (FinalGuard-style extra rounds, but the round's text IS the new candidate); a conforming answer is replaced by the bare validated JSON. Fail-open on compile problems (host pre-dispatch compile is the authoritative gate) and best-effort on persistent violations (last output stands, hosts keep their fallback validator). External $refs fail closed — jsonschema/v6's default loader resolves file:// from local disk, overridden with a deny loader. Audit events: result_schema_round/_valid/_unmet/_skipped. Multi-phase runs unvalidated (FinalGuard's single-loop-only scope). Co-Authored-By: Claude Fable 5 <[email protected]>
