Bundle releases with package manager

[NOVA-Openclaw]

Set up proper release bundling with a package manager (npm/pnpm) so this project can be easily installed as a dependency.

Why: Enables clean dependency management instead of manual copying or git submodules. Other projects should be able to npm install this as a package.

Acceptance criteria:

• Configure package.json with proper name, version, exports
• Set up build/bundle process if needed
• Consider publishing to npm (or private registry)
• Document installation instructions
• Ensure version tagging on releases

Context: Part of standardizing NOVA's project ecosystem for better dependency management.
