feat: publish 2.5.0 execution accounting (NVIDIA#308)

Publish the sanitized 2.5.0 public snapshot with execution ledger and completeness reporting.\n\nThis retains public GitHub workflows, public documentation, and the versioned release notes while excluding internal release tooling, provider implementation, and implementation-planning documents.\n\nVerification: the current internal main pipeline passed lint, unit, integration, Docker smoke, and Sonar. Snapshot integrity and diff checks passed; local tests were not rerun per release guidance.
