N/A

Summary of the issue:

The project currently lacks an automated testing workflow in CI to run unit tests using pytest.

Description of how this pull request fixes the issue:

This PR adds a new Test job to the GitHub Actions workflow (.github/workflows/build.yml).
It performs the following:

• Sets up Python 3.11 and installs uv.
• Installs all dependencies, including local architecture-specific packages (e.g., pytqsm).
• Generates necessary resources (app icons) required for GUI tests.
• Runs pytest to verify code quality.
• Adds pytest-github-actions-annotate-failures to annotates test failures directly in the PR.
• Configures the Build job to depend on the Test job, ensuring only passing code is built.

Testing performed:

• Validated locally on Windows environment: all 35 tests passed.
• Verified in CI (on the fork): The workflow correctly installs dependencies, generates resources, and executes tests.

Known issues with pull request:

None.
