terencecho a79d8acd7a fix: ship lottieReadiness + guard studio import.meta.env for non-Vite consumers (#861)
## Summary

Two small fixes that together make `@hyperframes/core` + `@hyperframes/studio` consumable from non-Vite hosts (Next.js / Turbopack, Node, etc.).

### 1. `core`: ship the missing `lottieReadiness` module

The `"./runtime/lottie-readiness"` subpath export in `@hyperframes/core` claims to ship at `./dist/runtime/adapters/lottieReadiness.js`, but that file is missing from the published 0.6.6 and 0.6.7 tarballs. Consumers that import the subpath — most notably `@hyperframes/studio`'s `Player.tsx` — fail to resolve the module and break downstream builds.

**Root cause:** `packages/core/tsconfig.json` excludes `src/runtime` (those files run in a browser context and are bundled separately into the IIFE artifact). Since nothing in the included tree imports `lottieReadiness.ts`, tsc never emits a compiled output, and the file silently goes missing from the publish.

**Fix:** `lottieReadiness.ts` is a pure helper — takes `unknown`, returns `boolean`, no DOM/`window` dependencies. It doesn't belong in `src/runtime/` in the first place; the runtime-exclude rule rightly caught it. Move it to `src/lottieReadiness.ts` so the standard library build picks it up.

The subpath export **name** stays `"./runtime/lottie-readiness"` — only the exports map's underlying file path changes — so existing consumers (studio) don't need any code change.

### 2. `studio`: guard `import.meta.env` for non-Vite hosts

`packages/studio/src/components/editor/manualEditingAvailability.ts` unconditionally reads `import.meta.env`. That's a Vite-only extension; in plain ESM hosts (Next.js / Turbopack, Node, jest in some configs) `import.meta` exists but `import.meta.env` is `undefined`. Reading any property off undefined throws at module evaluation time, so the studio fails to load the moment a non-Vite host imports anything from `@hyperframes/studio`.

Guarded the read so the module is loadable everywhere; outside Vite, every flag falls back to its declared default, preserving Vite behavior.

### Changes

**core:**
- `mv src/runtime/adapters/lottieReadiness.{ts,test.ts}` → `src/`
- Update `src/runtime/adapters/lottie.ts` re-export path
- Update `package.json` + `publishConfig.exports` to point at the new dist path (`./dist/lottieReadiness.{js,d.ts}`)

**studio:**
- One-line guard in `manualEditingAvailability.ts:30` with explanatory comment

## Test plan

- [x] `pnpm typecheck` (core, studio) — clean
- [x] `bun run build` (core) — `dist/lottieReadiness.{js,d.ts}` now present
- [x] `bunx vitest run` (core) — 862/862 passing
- [x] `bun run typecheck` (studio) — clean, resolves moved file via subpath export
- [ ] Publish 0.6.8 and verify the tarball contains `dist/lottieReadiness.js`
- [ ] Verify a non-Vite ESM consumer (e.g. a Next.js / Turbopack app) imports `@hyperframes/studio` without `import.meta.env` errors
