Greptile Summary

This PR updates the default Valkey image version used by the operator. The main changes are:

• Default Valkey image changed from valkey/valkey:9.0.0 to valkey/valkey:9.1.1.
• Controller and resource tests updated to use the new image tag.
• End-to-end test client image and documentation examples updated to match.

Confidence Score: 5/5

Safe to merge with minimal risk.

The change is a narrow image version bump across the default constant, examples, and tests. The new tag was verified as available, and the valkey-server and valkey-cli commands used by these paths remain available. No functional or security issues were identified.

Files Needing Attention: No files require special attention.

I believe this PR depends on resolving #337, i.e. changing the default will roll cluster nodes (that uses the default) without any gating or ordering.

Changes

Valkey image version update

Layer / File(s)	Summary
Default image and documentation internal/controller/valkeycluster_controller.go, docs/valkeycluster.md	The default controller image and private registry example now use Valkey 9.1.1.
Test fixture alignment internal/controller/*_test.go, test/e2e/*	Controller, resource, and end-to-end test images and assertions now use Valkey 9.1.1.

Merge Risk: 🔵 Low · up to 61912

This updates the default Valkey image to 9.1.1, which can roll existing clusters that rely on the default image. Rollout sequencing is expected to be readiness-gated, but coverage for this default-image upgrade scenario is still missing.

Add coverage for the default-image rollout path.

An empty spec.image can change existing nodes when DefaultImage changes. reconcileValkeyNodes already updates one node at a time, replica-first, and waits for Ready before advancing. Add a regression test with existing nodes on valkey/valkey:9.0.0 and an unset spec.image.
