Update Dependencies

[marchdoe]

This pull request primarily updates development dependencies across the project to their latest versions, adds package manager overrides for improved dependency control, and introduces tsconfig.json files to the react and vanilla packages for better TypeScript configuration and isolation.

Dependency updates:

• Updated various devDependencies to newer versions in the root package.json, including eslint, jest, prettier, rollup, and related plugins for improved linting, testing, and build tooling.
• Upgraded Babel, Webpack, and related dependencies in examples/react-webpack/package.json for improved build performance and compatibility.
• Updated Babel, ESLint, and Jest-related packages in packages/react/package.json and packages/vanilla/package.json to keep tooling current.

Dependency management improvements:

• Added a pnpm.overrides section to the root package.json to explicitly control versions of certain transitive dependencies, improving security and consistency.

TypeScript configuration:

• Added tsconfig.json files to both packages/react and packages/vanilla to extend the base configuration, specify included/excluded files, and, in vanilla, declare type definitions for node and jest.
