Removes ~30 stale "Phase N" / historical-staging comment references from code and shell scripts now that v1.0 is done; fixes a stale dashboard comment claiming applications/send-log were unimplemented; adds a CSRF ADR to security.md documenting the Origin-check-over-tokens decision; resolves docs/logo in roadmap.md (directory doesn't exist, criterion already met); adds a gofmt -l check to CI so unformatted Go fails the build. The known-limitations write-up for the log-tailer offset gap (the other Phase 1 item) was already present in architecture.md § Log tailer, so no change was needed there. gofmt/go vet/go test clean on both Go modules (main + test/e2e), verified on the dev server.
