fix(packages): declare @types/react as an optional peer dependency (#4892)

`lucide-react` and `lucide-react-native` both ship `.d.ts` files that
import React types (`ForwardRefExoticComponent`, `SVGProps`,
`RefAttributes`, `ReactNode`), but neither package declares
`@types/react`. Under a hoisted `node_modules` this resolves by
accident, so the gap is invisible in normal testing.

It does not resolve under a strict layout — most notably pnpm's global
virtual store (`enableGlobalVirtualStore`), where each package is linked
from a store path outside the consuming repo. TypeScript resolves a
package's imports relative to where that package physically lives and
ignores `NODE_PATH`, so `react` resolves to the untyped
`react/index.js`. Every icon's props silently degrade to `any`, and
consumers hit implicit-any errors on their own callbacks under
`noImplicitAny`. `skipLibCheck: true` hides the errors inside the
`.d.ts` itself, which is why this survives most typechecks.

Declaring the typings package as a peer dependency (rather than a hard
dependency) lets it dedupe against whatever `@types/react` the consumer
already has. `peerDependenciesMeta` marks it optional so JS-only
consumers get no unmet-peer warning.

Verified by packing each package and installing the tarball into a
scratch consumer with `pnpm --virtual-store-dir` pointing outside the
consumer, then typechecking with `skipLibCheck: false` and a
`@ts-expect-error` probe on a nonexistent icon prop — a positive type
assertion keeps passing when types widen to `any`, so it would not
catch a regression. Before the change the probe reports
`TS2578: Unused '@ts-expect-error' directive` plus `TS7016` inside the
shipped `.d.ts`; after it, `tsc` is clean and `--traceResolution`
shows `react` resolving to `@types/react/index.d.ts` instead of
`react/index.js`. Existing peer ranges are unchanged and the lockfile
is unaffected.
