internal/agent/service: build-tagged into service_windows.go (svc.Handler that listens for Stop/Shutdown + delegates to the agent loop) and service_other.go (foreground stub for Linux/macOS). install_windows.go wraps mgr.Connect+CreateService/Delete/Start/Stop for the new 'restic-manager-agent install|uninstall|start|stop' subcommands. Cross-compile verified: GOOS=windows GOARCH=amd64 go build ./cmd/agent succeeds. UNTESTED on Windows itself — the SCM round-trip can't be exercised from Linux CI; treat as a starting point for the first real Windows install.
