Scooby HuskyandClaude Sonnet 5 83c06a888d GitLab cross-site replication Phase 1c (stage 1): VPS clusters as real replicas
Replaces VPS's independent standalone pg-gitlab (own initdb, own
root/Scooby test data - never meant to survive this, per the approved
plan) with a bootstrap.recovery replica of home's, matching the
pg-authentik precedent. New pg-praefect cluster on the VPS too (never
existed before - VPS ran Gitaly without Praefect).

Stage 1 of 2: recovery-only, no streaming replication config yet - that
needs this cluster's own CNPG-generated certs to exist first, which
only happens once CNPG actually creates the cluster. Stage 2 (next
commit) copies certs cross-cluster and adds externalClusters
connectionParameters + replica.self/primary/source to all four Cluster
CRs (home pg-gitlab/pg-praefect, VPS pg-gitlab/pg-praefect).

postgresql.parameters copied verbatim from home's manifests (must
match-or-exceed, confirmed live for pg-authentik). vps-minio-secret
created manually on the VPS (kubectl, not git - same as every other
cross-cluster secret in this plan) pointing at the VPS's own local
MinIO, which now holds home's pg-gitlab/pg-praefect base backups
(triggered manually via Backup CRs since neither had run yet).

# 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.
