# =============================================================================
# CI - Continuous Integration
# =============================================================================
# Runs on every push and pull request to ensure code quality.
#
# Jobs:
#   - lint: Check code formatting and style
#   - test: Run test suites (Haskell, OCaml)
#   - build: Verify everything compiles
#
# All jobs use actions/checkout@v6.0.1 (current stable version as of 2024)
# =============================================================================
