Add CI/CD pipeline and improve package metadata

[amavashev]

Summary

This PR establishes a complete CI/CD pipeline for the project and enhances the package.json metadata to better represent the project on npm and GitHub.

Key Changes

• Added GitHub Actions CI workflow (.github/workflows/ci.yml)

  • Runs tests on Node.js 20 and 22 for all pushes to main/master and pull requests
  • Includes typecheck and build steps to catch issues early
  • Automated npm publishing on version tags with provenance support

• Enhanced package.json metadata

  • Added author, repository, homepage, and bugs fields for better discoverability
  • Added relevant keywords (cycles, budget, billing, metering, api-client, ai, llm, runcycles)
  • Removed unused run dependency from dependencies

Notable Details

• The publish job only triggers on tags matching the v* pattern, following semantic versioning conventions
• Uses npm provenance for enhanced security during package publication
• CI runs on ubuntu-latest with npm caching for faster builds
• Minimal permissions principle applied with explicit permission grants per job
