Fix 16 golangci-lint issues breaking CI

Pre-existing lint issues across 10 files: govet (redundant \n in
Println, Sprintf with unused arg), ineffassign, staticcheck (S1000
single-case select, ST1005 capitalized errors, SA9003 empty branch,
QF1003 if-else to switch, QF1008 embedded field selector), and
unused vars/funcs.

All 16 issues resolved. go build ./... and go vet ./... pass clean.
