Add Layer-1 thread-safety invariant specs

Two deterministic tests that turn the validation layer's concurrency
invariants into permanent regression guards — no timing or thread
interleaving involved, so no flakiness:

- Frozen-graph canary: walks every object reachable from the compiled
  routes' validator lists (validators, iterators, scopes, coercers —
  including oneof variant validators reached through nesting) and
  asserts each contract-class instance is frozen. Catches classes that
  never adopted the FreezeOnNew contract, not just regressions in those
  that did. A census assertion proves the walk actually swept the whole
  taxonomy, and a self-test proves the walker reports unfrozen objects.

- Cache growth canary: snapshots every Grape::Util::Cache key set after
  definition + compile!, then fires first-ever requests (valid, invalid,
  wrong-shape, 404, OPTIONS, 405) and asserts no cache gained keys.
  Pins the "caches are written only at boot" property that makes their
  unsynchronized reads safe; would have caught the pre-#2817
  ArrayCoercer seeding DryTypes::ParamsCache on first request.

Test-only; no production changes.
