# CI — Unit Tests + NativeAOT Build
#
# Runs on every push and PR. Fast feedback loop (~2-3 min).
# - Node.js unit tests on Ubuntu + Windows
# - C# build + NativeAOT publish on Windows
# - Test report generation and artifact upload
#
# Integration tests (requiring M365 credentials) run separately
# via integration.yml on manual dispatch or nightly schedule.
