Summary

Implements Issue #17 — Automated GitHub Actions CI/CD Pipeline. Sets up linters, static type checkers, dependencies safety scanners, and unit testing runs with coverage criteria.

Changes

CI/CD Workflow configuration

• Created .github/workflows/ci.yml defining:
  • Runs on push/PR targeting main and development branches.
  • Strategy matrix covering platforms (ubuntu-latest, windows-latest) and Python versions (3.11, 3.12).
  • Automated apt-get system dependencies installation for Linux runners (libportaudio2 and libasound2-dev required by sounddevice).
  • Python dependencies installation including optional feature packages ([dev,nlp,whisper]).
  • Code linting via ruff check src/.
  • Static type checking via mypy src/.
  • Dependency vulnerability scan via safety check.
  • Headless unit testing on Ubuntu using xvfb-run wrapping pytest to support customtkinter GUI frame initializations.
  • Automated test runs requiring at least 80% coverage: pytest --cov=src --cov-fail-under=80.

Dependencies & Exclusions

• Added safety to development dependencies block in pyproject.toml and requirements-dev.txt for consistency.
• Updated .gitignore to exclude local coverage files and test caches (.coverage, .pytest_cache, .mypy_cache, .ruff_cache).

Verification Results

• Executed linting, typing, security scanning, and coverage checks locally:
  • Ruff: All checks passed (ruff ✓)
  • Mypy: All checks passed (mypy ✓)
  • Safety: Checked environment (safety ✓)
  • Pytest: 150/150 unit tests passed with 83.59% coverage (exceeding the 80% limit threshold!).
