fix: correct exports map ordering

Context

1. In Add render-diff and render-fixture subpath exports + MDX↔MDXish regression suite #1489 we added an exports map to support new regression test exports

   markdown/package.json

   Lines 9 to 26 in 928b36e

   	"exports": {
   	".": {
   	"types": "./dist/index.d.ts",
   	"browser": "./dist/main.js",
   	"node": "./dist/main.node.js",
   	"default": "./dist/main.node.js"
   	},
   	"./render-diff": {
   	"types": "./dist/lib/render-diff/index.d.ts",
   	"default": "./dist/render-diff.node.js"
   	},
   	"./render-fixture": {
   	"types": "./dist/lib/render-fixture/index.d.ts",
   	"default": "./dist/render-fixture.node.js"
   	},
   	"./package.json": "./package.json",
   	"./*": "./*"
   	},

   But the map listed "browser" first. Some tools (like Jest, when testing React components) ask for both "browser" and "node" at once so Jest kept receiving the browser file when it needs the node file.

2. This caused these test failures in the monorepo https://github.com/readmeio/readme/actions/runs/28407377427/job/84174978249?pr=19434

3. We added this fix which forces jest to use the node file. But a simpler fix is to just re-order the entries in the @readme/markdown package

🎯 What does this PR do?

• Fix the ordering of entries so we can clean up the monorepo bandaid
• Export some types so we can use them correctly in the monorepo

Walkthrough

This change adds TypeScript type re-exports for MdxishOpts, RenderMdxishOpts, and RunOpts in index.tsx and RunOpts in lib/index.ts, extending the module's public API surface. Additionally, package.json's exports["."] condition map was updated to list the node condition before the browser condition, reversing their previous order.

Changes

Area	Change
index.tsx	Added export type { MdxishOpts, RenderMdxishOpts, RunOpts } from './lib'
lib/index.ts	Added export type { RunOpts } from './run'
package.json	Reordered node/browser entries in exports["."]

Poem
A rabbit hops through types anew,
RunOpts and Mdxish peeking through,
Node now leads where browser led,
Exports reordered, cleanly bred,
Small hops, big API view. 🐇
