Fixes #2988. Brings 'golangci-lint run ./...' to zero issues (was ~373): - errcheck: explicitly ignore fire-and-forget calls with '_ =' (and a small errcheck.exclude-functions list for response writes — json Encoder.Encode, http ResponseWriter.Write, fmt.Fprint*); genuine cases handled. - unused: remove dead code (unexported decls and dead test helpers) and the imports they orphaned. - staticcheck: ST1005 error strings, ST1016 receiver names, S1000/S1017/S1019/ S1023 simplifications, SA4004/SA4006/SA4010 dead code, SA1021 net.IP.Equal, SA6002 (store *[]byte in sync.Pool). - govet: fix a context leak (lostcancel) in internal/util/mdns and move t.Fatal/Fatalf out of goroutines (testinggoroutine) in tests. - ineffassign, unconvert: mechanical fixes. CI: the Lint workflow now runs a blocking full-tree 'golangci-lint run' on pushes and PRs (dropped only-new-issues now that the tree is clean). Verified: go build, go vet, test compilation, and unit tests for the behaviourally-touched packages all pass.
