Subject: [PATCH] ci: add PR-gate workflow and golangci-lint config

The repo had no `on: pull_request` CI (only workflow_dispatch + nightly
schedule), so nothing validated PRs. Add `.github/workflows/pr.yml` that
builds libwaku and runs `go build`, `go vet`, golangci-lint, and a test-compile
pass on every PR. Add a baseline `.golangci.yml` (standard linters + gofmt).
