fix: remove unused runtime dependencies

[teneplaysofficial]

This PR refactors the project's package.json by moving development-only modules out of dependencies and into devDependencies, ensuring that only true runtime packages are installed in production environments.

Previously, several build tools and development utilities were incorrectly listed as production dependencies. This resulted in:

• Unnecessarily heavy production installs
• Slower CI and contributor setup times
• Reduced dependency clarity and maintainability

Improvements in This PR

• Smaller, faster production installs
  Only the modules required to run the package remain in dependencies.

• Proper separation of development vs runtime concerns
  Build, test, and type tooling now live exclusively under devDependencies.

• Reduced published package footprint
  Consumers no longer download unnecessary tools.

• Cleaner dependency hygiene
  Aligns with npm and open-source best practices for libraries and CLIs.
