Move tsconfig.json to project root

The packages/core/tsconfig.json only covered packages/core/src,
leaving packages/react and packages/node-legacy without a TypeScript
project context. This caused type errors in their types.d.ts files
that reference global types (GeneratorMetadata, Generate, ProcessChunk)
declared in packages/core/src/generators/types.d.ts.

A root tsconfig.json with include: ["packages/*/src"] ensures all
packages share a single compilation context where the global type
declarations are visible everywhere.
