# TaskFlow CI Pipeline
#
# Runs on every push and pull request to the main branch:
#   1. Lint — go fmt + go vet
#   2. Test (race) — all unit + integration tests with the Go race detector
#   3. Binary build — produces the taskflow binary and runs a smoke test
#
# Targets delegate to the Makefile for consistency between local and CI.
