Key changes:

• Build and runtime chain updates:
  • Updated role image build/runtime scripts (build.sh, start-single.sh, start-dual.sh, config.json).

  • Bundled SDK/runtime assets into repository (build-assets/sdk-source, executor runtime, manifest updates).
  • Refactored image build path to reduce dependency on external asset sources.
• Config and security hardening:
  • Externalized sensitive keys/endpoints and runtime base URLs via .env / .env.example.
