jsr.json file in Zod codebase

jsr packages need to contain a configuration file that specifies the name, version and exports of a package. This file should be name jsr.json or jsr.jsonc.

{
  "name": "@zod/zod",
  "version": "4.0.0-alpha.0",
  "exports": {
    ".": "./src/index.ts",
    "./package.json": "./package.json"
  },
  "publish": {
    "include": ["src", "LICENSE", "package.json", "README.md"],
    "exclude": ["tests", "dist"]
  }
}
