--- name: make-check description: Run full pre-commit validation (fmt, lint, test, security) and report results --- Run `make check` in the project root and report the results. If any step fails, diagnose the first failure and suggest a fix. Do not proceed to later steps if an earlier one fails — focus on resolving the first issue. The steps run by `make check` are: 1. `make fmt` — gofmt formatting 2. `make lint` — go vet + golangci-lint 3. `make test` — all tests with race detector 4. `make security` — gosec + govulncheck
