feat: optimize CI/CD with Nx Cloud distributed execution and artifact sharing

- Enable Nx Cloud distributed task execution with 6 agents for parallel builds
- Increase parallel execution from 3 to 6 to match site count
- Add .docusaurus to build cache outputs for better caching
- Replace matrix build strategy with nx affected commands for efficiency
- Fix artifact sharing between CI jobs to resolve sitemap validation failures
- Generate Nx dependency graph and performance report for monitoring
