Detailed Description of the Pull Request / Additional comments

Validation Steps Performed

[Copilot]

🔵 Needs a closer look

It changes CI test selection/sharding and pipeline orchestration logic in ways that require human validation of coverage and runtime behavior across images/suites.

Pull request overview

Refactors CloudTest map/group generation and Azure Pipelines test orchestration to prototype more efficient CI by parameterizing artifact providers/build-file copies and sharding WSL2 test execution into smaller suites.

Changes:

• Replace hardcoded CloudTest providers and BuildFiles entries with CMake-generated conditional blocks (e.g., package artifact + optional test packages/unit tests/test data).
• Add new WSL2 sharded CloudTest suites (unit, e2e shard 1, e2e shard 2) via TAEF /select filters.
• Update Azure Pipelines templates to iterate over richer test_suites objects and route to the correct CloudTest map path/display name.

🔵 Needs a closer look

It refactors CI/CloudTest job generation and test suite sharding in ways that could silently change what artifacts are fetched and which tests execute, so it needs human validation in CI.
