Subject: [PATCH] fix: Ship compiled test mock entry point

Minimal fix for `@expensify/react-native-live-markdown` compatibility in React Native 0.87+ projects that wire up the test mock from a TypeScript setup file. See https://github.com/react-native-community/template/issues/245.

**Context**

React Native 0.87 ships the Strict TypeScript API by default (moving to a user opt-out).

Typically, this change is scoped to the user's project (`@react-native/typescript-config` includes `skipLibCheck: true`) and does not reach library source code.

However, this library ships a Jest mock at `@expensify/react-native-live-markdown/mock`, which is an exception that crosses this boundary.

**Problem**

`@expensify/react-native-live-markdown/mock` resolved to raw `mock/index.ts` — no sibling `.d.ts` existed at that path — so it pulled this library's `../src/*` into the scope of the user's TypeScript analysis instead of the compiled `lib/` code. That produces a type error against deep imports such as `react-native/Libraries/Types/CodegenTypes`, which no longer resolve under the Strict TypeScript API (`TS2307`). `skipLibCheck` does not contain it because it does not apply to `.ts`/`.tsx`.

**This diff**

Move the mock into the builder-bob build so consuming projects only ever see this library's `.d.ts` files, which are exempt from typechecking.

- Move `mock/index.ts` to `src/mock/index.ts` so builder-bob compiles it like the rest of the library; repoint its imports from `'../src'` to `'..'`.
- Preserve the `@expensify/react-native-live-markdown/mock` subpath via shims: `mock/index.js` re-exports `../lib/commonjs/mock/index.js`, `mock/index.d.ts` re-exports `../lib/typescript/src/mock/index`.
- Drop `mock/**/*` from tsconfig `include` so the source is only picked up under `src/`, and lint-ignore `mock/**/*` since the shims point into build output.

No `exports` map is introduced — the package has none today, and shims are the conservative, non-breaking equivalent.

Changelog: [Fixed] - Ship a compiled `/mock` entry point so consumers resolve declarations instead of raw source
