fix(clickstack-operators): bump clickhouse-operator-helm dep to >=0.0.5

[ZeynelKoca]

Problem

The clickstack-operators chart at v1.0.0 declares its clickhouse-operator-helm dependency as ~0.0.2. In Helm's Masterminds semver implementation, the tilde range for pre-1.0 patch-level versions is interpreted narrowly as >=0.0.2 <0.0.3 — so this dep resolves only to v0.0.2 of the operator chart, even though newer 0.0.x releases (v0.0.3, v0.0.4, v0.0.5) exist.

Consumers of clickstack-operators v1.0.0 are effectively pinned to operator v0.0.2 and miss every fix since then. In particular, v0.0.5 ships:

• New CRD schema field spec.podDisruptionBudget on both ClickHouseCluster and KeeperCluster (lets users override the auto-generated PDB).
• Smart default for ClickHouseCluster with replicas <= 1: maxUnavailable=1 (instead of minAvailable=1) so single-replica clusters do not deadlock on voluntary disruption (e.g. node drains, upgrades).
• RBAC additions (notably the Jobs informer the v0.0.5 controller manager requires).

We hit this in production: a single-replica deployment of ClickStack on AKS got stuck on a node-pool VM resize because the v0.0.2 operator generated PDBs that no eviction could satisfy (minAvailable=1 on a 1-replica ClickHouse, maxUnavailable=0 on a 1-replica Keeper). Bumping the wrapper chart's operator image alone is not enough — the v0.0.5 binary crashloops against v0.0.2's RBAC/CRDs.

Fix

Widen the dependency constraint so the chart pulls v0.0.5 (and stays compatible with future 0.0.x releases):

# charts/clickstack-operators/Chart.yaml
- name: clickhouse-operator-helm
  version: ">=0.0.5, <0.1.0"   # was: "~0.0.2"

This pulls operator v0.0.5 + its matching CRDs + matching RBAC together, as one consistent set.

Verification

$ helm dependency build charts/clickstack-operators
Pulled: ghcr.io/clickhouse/clickhouse-operator-helm:0.0.5

$ helm template clickstack-operators charts/clickstack-operators | grep -c "^kind:"
29

Resolves cleanly, no template errors, all expected resources render.

Changeset

Added .changeset/bump-clickhouse-operator-helm.md (minor bump) describing the user-visible change for the next release.

Notes for adopters

Existing installations have CRDs with helm.sh/resource-policy: keep (from the original install), which prevents Helm from updating them on upgrade. After this change merges and a new chart release is published, adopters upgrading from v1.0.0 will need a one-time kubectl apply -f of the new CRDs (or remove the keep annotation) to pick up the new schema. This is unrelated to this PR but worth mentioning in the release notes.

@dhable Any indication on when this can be merged + released? Running into production upgrade issues now, which we had to find a temporary solution for.
