Stop bundling @cfworker/json-schema into the main package barrel. Previously CfWorkerJsonSchemaValidator was re-exported from the core internal barrel, so tsdown inlined the @cfworker/json-schema dependency into every consumer's bundle even when it was never used. The named validator classes are now reachable only via the explicit @modelcontextprotocol/{client,server}/validators/{ajv,cf-worker} subpaths and the runtime _shims conditional, so consumers that import only from the root entry point no longer ship the validator dep.
