Zod V4 Updates - Zodix React Router

[resquino-truefit]

Add zod v4 support via dual entry points

Summary

Adds a second entry point (@zreott-tf/zodix-react-router/v4) so consumers can use this package with zod v4 schemas, while keeping the existing default entry point (@zreott-tf/zodix-react-router) working for zod v3 schemas — no breaking change to the existing API surface, just a new import path.

What changed

• src/v4/ (new): mirrors parsers.ts and schemas.ts, importing from the zod/v4 compat subpath instead of zod/v3. Re-exports the same zx API (parseParams, parseParamsSafe, parseQuery, parseQuerySafe, parseForm, parseFormSafe, BoolAsString, CheckboxAsString, IntAsString, NumAsString).
• src/parsers.ts, src/schemas.ts: switched from import { z } from 'zod' to import { z } from 'zod/v3', pinning the default entry point to zod's v3-compat subpath explicitly.
• build.js: added a second esbuild.buildSync pass bundling src/v4/index.ts → dist/v4/index.js, with zod/zod/v4 kept external.
• package.json:
  • Added an exports map with . and ./v4 conditions (each with their own types/default).
  • Bumped the zod devDependency to ^4.4.3 and widened the zod peerDependency to ^3.0.0 || ^4.0.0.
  • Version bump 0.1.0 → 0.2.0.
• tsconfig.json: moduleResolution changed from node to bundler (plus module: esnext) — required so TypeScript respects the exports/types conditions on the zod/v3 and zod/v4 subpaths; the old node resolution mode ignores them.
• Tests: existing parsers.test.ts/schemas.test.ts updated for the zod/v3 import; new src/v4/parsers.test.ts/src/v4/schemas.test.ts added, exercising the same suite against zod/v4.

Note

• A follow-up PR to make use of the updated Zodix React Router within the Truefit Stack is ready as soon as this PR merges

I think we can save the version bump until we release this. The np tool in the release script had me update it as part of the workflow.
