# Makefile — exo build, test, lint, and release targets
#
# Usage:
#   make build      — compile all binaries to bin/
#   make test       — run tests with race detector
#   make vet        — run go vet
#   make lint       — run golangci-lint
#   make all        — vet -> lint -> test -> build (CI pipeline)
#   make generate   — regenerate protobuf stubs (requires protoc)
#   make clean      — remove bin/ and generated artifacts
