Bumping CI to v2.5.0 surfaced two new gofumpt findings (in two test files that gofumpt v2.1.6 considered fine). Local re-format with the matching tool brings them in line. Pre-commit hook config: prepend $GOPATH/bin to PATH inside the hook entry so gofumpt + golangci-lint resolve when ~/go/bin isn't on the operator's interactive shell PATH (common — go install puts them there but PATH config varies). Without this, the hooks fail with 'Executable not found' even when the tools are installed. Pin the Makefile setup target to v2.5.0 so a fresh clone gets the same binary CI runs — keeps pre-commit and CI from drifting again.
