build: migrate build system to Vite and test runner to Vitest & Remove depracated husky usage (#2703)

- Replace Webpack with Vite for faster client bundling and HMR.
- Migrate tests from Jest to Vitest and update configuration.
- Update Web Worker instantiation to standard ESM syntax.
- Implement Env utility in `src/core` for safe, hybrid environment
variable access (Vite vs Node).
- Refactor configuration loaders to remove direct `process.env`
dependencies in shared code.
- Update TypeScript environment definitions and project scripts for the
new toolchain.
- Remove the [depracated usage of the
husky](https://github.com/typicode/husky/releases/tag/v9.0.1).
