__NAME__ — one-line description of what this workflow checks.

Go-profile scaffold: run PATH-checks `go` (exit 2 if missing) and then
runs `go vet ./...` as an inert default. Replace the vet call with the
actual check this workflow needs. It executes with the repository root
as the working directory and the EECO_* variables in the environment.

Exit codes: 0 clean, 1 finding, 2 blocked (a required tool is missing),
3 AI pass deferred (no --ai).
