<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Low risk release bookkeeping (version/changelog/image tag bumps) with
no functional code changes; primary risk is mismatched image tags
causing CI/deploy/test failures if any reference was missed.
> 
> **Overview**
> **Prepares the `3.0.5` release.** Updates `VERSION` and `CHANGELOG.md`
with a `3.0.5` entry noting a `google.golang.org/grpc` security fix
(CVE-2026-33186).
> 
> Propagates the `3.0.5` tag across operational artifacts by bumping the
`mimirtool` base image in `operations/mimir-rules-action/Dockerfile` and
updating all generated `operations/mimir-tests/*` manifests to use
`grafana/mimir:3.0.5` instead of `3.0.4`.
