1.13.0: measure + evidence compose; value-graph now a registry dep

- DSLValueGraph integrates the evidence DSL with @arbiter/value-graph: measures
  become typed value-graph nodes; attach() wires runtime.measure through the graph.
- DSLRuntime.check() now retrieves required MEASURE values and injects them as
  value-carrying self-edges, so an evidence comparator over a measure (e.g.
  budget_used(user) <= budget_limit(user)) evaluates — measure and evidence
  compose (provider-sourced AND value-graph-sourced), with 3 new composition tests.
- BUILTIN_TYPES: bigint → buffer (the value-graph wire is JSON-free/bigint-free).
- @arbiter/value-graph: file:../value-graph → ^0.1.0 (registry); CI auth adds
  @push-stream-std registry for the transitive dep.
- rigor core ^3.1.2 / probe ^0.0.8.
