Go 1.27 ships a standard-library uuid package (RFC 9562), making the github.com/google/uuid dependency unnecessary. This bumps the toolchain to 1.27 and migrates all UUID usage to the stdlib.

Toolchain

• go 1.27.0 in both go.mod (root) and cmd/sshpiperd/go.mod
• go-version: '1.27.x' in .github/workflows/test.yml and release.yaml
• golang:1.27-bookworm builder in Dockerfile
• go.work example in .github/copilot-instructions.md bumped to go 1.27

UUID migration

• Import swapped from github.com/google/uuid to stdlib uuid across the daemon, the revtunnel plugin, and e2e tests
• uuid.NewRandom() → uuid.New(); the stdlib constructor cannot fail, so the surrounding error plumbing is dropped
• uuid.NewString() → uuid.New().String()
• uuid.Parse is API- and format-compatible (plain, braced, urn:uuid:, unhyphenated), so isGeneratedGUID is unchanged
• github.com/google/uuid is no longer a direct requirement in either module; it remains indirect via k8s deps

// cmd/sshpiperd/internal/plugin/grpc.go
uiq := uuid.New()

meta := PluginConnMeta{
    ConnMeta: libplugin.ConnMeta{
        UniqId: uiq.String(),
        ...

🟡 Changes recommended

The Go 1.27 bump currently prevents the required Go CodeQL analysis from building either module.

The latest Go CodeQL check still fails under Go 1.26.6, while the replacement workflow remains blocked pending approval and default-setup reconfiguration.

🔵 Needs a closer look

Required build and E2E checks remain in progress, so the toolchain and plugin changes are not fully validated.
