Adds externalClusters connectionParameters + replica.self/primary/source to all four Cluster CRs (home pg-gitlab/pg-praefect, VPS pg-gitlab/pg-praefect), turning last commit's recovery-only replicas into real CNPG streaming replicas - exact pattern already proven for pg-authentik. TLS certs copied cross-cluster manually (kubectl, not git, same as every other cross-cluster secret in this plan). Also adds pg-gitlab-app/pg-praefect-app password sync (PushSecret home -> Vault -> ExternalSecret VPS, Merge policy) - CNPG-generated passwords stay in sync via WAL replication but the K8s Secret OBJECTS never resync on their own, same gap already closed for pg-authentik-app. VPS's standalone clusters were already destroyed and recreated as recovery-mode replicas in the prior commit (with the user's explicit help running the classifier-blocked kubectl delete) - this commit turns on the actual streaming replication on top of that.

# GitLab cross-site replication Phase 1c (see
|
|
# /home/scooby/.claude/plans/jiggly-snacking-iverson.md) - the VPS never
|
|
# had a pg-praefect cluster before (VPS ran Gitaly without Praefect,
|
|
# global.praefect.enabled: false). This is new, matching home's
|
|
# apps/gitlab/manifests/praefect-cnpg-cluster.yaml as a real replica.
|
|
#
|
|
# Same two-stage deployment as cnpg-cluster.yaml in this directory: this
|
|
# commit is bootstrap.recovery only, streaming config added once this
|
|
# cluster's own certs exist to copy cross-cluster.
