feat(ssh,wincertstore,javakeystore,k8ssecret): explicit ValidateOnly + leverage existing connectors
Phase 9 of the deploy-hardening I master bundle. The four non-file-server connectors get real ValidateOnly probes that operators use to preview a deploy without touching the live cert. Existing DeployCertificate paths already have explicit backup + rollback semantics (SCP backup / WinCertStore Get-ChildItem snapshot / keytool snapshot / K8s atomic API). SSH (validate_only.go): - Probes via SSHClient.Connect. Confirms agent reachability + credentials. Cheap (no remote command runs); released cleanly via defer Close. - A true SCP dry-run requires a no-commit upload (SCP doesn't have one). V2 ships the auth probe as the load-bearing check. - 3 new tests in validate_only_test.go. WinCertStore (validate_only.go): - Probes via PowerShell `Get-ChildItem -Path Cert:\<loc>\<store>` using the configured StoreLocation + StoreName (defaults LocalMachine\My). - Confirms agent has Windows + the IIS module + the right ACLs. - 4 new tests including default-store-path verification. JavaKeystore (validate_only.go): - Probes via `keytool -list -keystore <path> -storepass <pass>` using the configured KeystorePath / KeystorePassword and KeytoolPath (default "keytool"). - Confirms keystore exists, password is correct, JRE is on PATH. - 4 new tests covering succeeds / fails / no-path-sentinel / nil-executor-sentinel. K8s Secret (validate_only.go): - Probes via K8sClient.GetSecret on the configured Namespace + SecretName. Returns nil on success or "not found" (the CreateSecret path on Deploy will handle it). Other errors (forbidden/unreachable) surface as wrapped. - 4 new tests covering succeeds / RBAC-error wrapped / no-config-sentinel / nil-client-sentinel. Smoke test connectorsAtPhase3 list shrunk from 7 to 3 entries (ssh + wincertstore + javakeystore + k8ssecret removed). Only caddy (file-mode) + envoy + traefik remain — those three genuinely have no validate-with-target command available. Race detector clean across all 13 connectors. golangci-lint v2.11.4 clean. Phase 10 next: DeployCounters + Prometheus exposer mirroring the production-hardening-II OCSP counter pattern.
