Feat: devcontainer pytest integration

[junkataoka]

This pull request introduces a major refactor and modernization of the CI pipeline infrastructure for both Azure DevOps and GitHub Actions. The main improvements are the switch to modular, template-driven pipeline definitions, enhanced support for devcontainer-based testing, and improved code coverage reporting. The changes streamline CI setup, make it easier to add new projects, and improve compatibility across platforms (Linux and macOS). Documentation and configuration files have also been updated for clarity and consistency.

Azure DevOps Pipeline Modernization

• Both .azuredevops/ado-ci-pipeline-ms-hosted.yml and .azuredevops/ado-ci-pipeline-self-hosted.yml are refactored to use a two-stage pipeline (Lint and Test), with jobs and steps defined via new templates for devcontainer testing and coverage publishing. This replaces legacy scripts and direct task definitions, making the pipeline more maintainable and extensible. [1] [2] [3]

Template-Driven CI Architecture

• New reusable templates are introduced under .azuredevops/templates/, including test-devcontainer-job.yml for per-project devcontainer testing, run-devcontainer.yml for platform-aware container execution, setup-devcontainer.yml for environment setup, publish-test-results.yml for publishing test results and coverage, and merge-coverage.yml for merging and publishing code coverage reports. [1] [2] [3] [4] [5]

GitHub Actions Pipeline Improvements

• .github/workflows/ci.yaml is reworked to use matrix jobs for devcontainer-based testing, artifact upload for results and coverage, and a dedicated lint job. A new job aggregates and publishes combined test results and coverage reports, improving visibility and maintainability. [1] [2]

Documentation and Configuration Updates

• References to legacy scripts (e.g., ci-tests.sh) are removed from README.md and .env.example is updated for clarity, reflecting the new devcontainer and pipeline workflow. [1] [2] [3]

Platform Compatibility and Usability Enhancements

• The new pipeline templates include logic for handling both Linux and macOS (Apple Silicon) agents, and ensure clean workspace setup and artifact handling for reliable CI runs. [1] [2]
