Convert project from `ts-node` to native TypeScript support in Node.js

[Alex-AK]

We’re looking to modernize our TypeScript setup by switching from ts-node (and tsc) to Node.js’s native TypeScript support, as outlined in the official guide:
🔗 https://nodejs.org/en/learn/typescript/run-natively

Goals

• Remove dependency on ts-node and typescript as a build step
• Use .ts files directly with Node.js runtime
• Simplify dev tooling and startup scripts

Tasks

• Remove ts-node, typescript, and any related dependencies (unless still needed for type-checking or other tooling)
• Update package.json scripts to use node --loader tsx or similar
• Refactor imports (e.g., ensure use of file extensions like .js if needed)
• Ensure compatibility with ESM (if the project uses it)
• Update documentation (README.md, contributing guides, etc.)
• Test dev and prod workflows

References

• [Node.js Native TypeScript Docs](https://nodejs.org/en/learn/typescript/run-natively)
• [tsx loader](https://github.com/esbuild-kit/tsx) (commonly used for fast native support)

Why?

• Native TypeScript support improves cold start performance
• Reduces dependency surface
• Aligns with evolving Node.js ecosystem
