Pull request overview

This pull request introduces a significant architectural improvement by splitting Docker images into base and product variants to optimize build times and reduce GitHub Actions cache utilization. The project version is updated to 2.10, and comprehensive refactoring has been applied to support the new architecture.

Changes:

• Introduced two base Docker images (ptr727/nx-base:ubuntu-noble and ptr727/nx-base-lsio:ubuntu-noble) containing common packages, which are used as FROM images for all product Dockerfiles
• Refactored C# codebase to use strongly-typed enums (BranchType, BaseType, ProductType) with lowercase JSON serialization for Matrix.json
• Updated all bash scripts to use set -euo pipefail for stricter error handling
• Improved GitHub Actions workflows with new base image build step and optimized cache strategies
• Replaced external download.sh script with inline bash in Dockerfiles for better maintainability
