feat(zod): support JSON schema registries

[dinwwwh]

Brings the v1 JSON_SCHEMA_REGISTRY, JSON_SCHEMA_INPUT_REGISTRY, and JSON_SCHEMA_OUTPUT_REGISTRY to @orpc/zod v2, so users can customize the generated JSON schema per Zod schema.

import { JSON_SCHEMA_REGISTRY } from '@orpc/zod'

const user = z.object({
  name: z.string(),
  age: z.number(),
})

JSON_SCHEMA_REGISTRY.add(user, {
  examples: [{ name: 'John', age: 20 }],
})

• Registry entries are merged over the generated schema at any nesting level; direction-specific registries take precedence over the general one, matching v1 behavior.
• Registries are typed with $input/$output, so examples, default, etc. are checked against the schema's input/output types.

Reviewed changes — added v1-style typed JSON Schema registries to @orpc/zod so users can customize generated schemas, with direction-specific registries taking precedence over the general one.

• Added JSON_SCHEMA_REGISTRY, JSON_SCHEMA_INPUT_REGISTRY, and JSON_SCHEMA_OUTPUT_REGISTRY backed by Zod's native registry() helper.
• Updated ZodToJsonSchemaConverter to merge registry entries over generated schemas via Object.assign during toJSONSchema's override callback.
• Made JsonSchema<Value = any> generic so registry entries can type-check examples/default against a schema's input/output shape.
• Added runtime tests for merging, direction precedence, and nested-schema application, plus type tests for registry value shapes.
