### Conflicts resolved by hand

- [#3735](#3735): only
`pkg/config/config_test.go` conflicted. release-1.6 has no
`HelmServerSideApplyAnnotation`, so that test entry is left out, and two
comments in `pkg/config/config.go` and
`internal/controller/applicationdefinition_controller.go` are adjusted
to what exists on this line. The rest is the original as is.

Checked on this branch before opening: `helm template` of
`monitoring-agents` and `vm-instance-rd`, `go build`, `go vet`, `go
test` and the commit trailer check pass. Not run locally: `helm
unittest` (plugin not installed) and `helm template` of `harbor`,
`kubernetes` and `tenant`, which need values to render at base and head
alike. CI runs the unit suites.

Not a UI change.

### Release note

```release-note
fix(kubernetes): the tenant CSI HelmRelease now retries a failed install instead of being uninstalled between attempts, so a failed install no longer takes the tenant's CSI node plugin and its propagated StorageClasses away while it retries. The same strategy applies to the upgrade action, which it has to: a retried install runs as an upgrade. One consequence is operator-visible: a failed CSI upgrade in a tenant cluster now retries the new manifests every 30s instead of rolling back to the previous release.

fix(harbor): retry a failed Harbor install instead of uninstalling the release, so a slow first install no longer deletes the Redis volume and starts over

fix(tenant): retry a failed etcd or seaweedfs install instead of uninstalling the release, so a slow first install no longer runs the cleanup hooks that delete the etcd data volumes, the SeaweedFS volumes and the filer metadata database

fix(vm-instance): VMInstance HelmReleases no longer hang InProgress or roll back healthy VMs; the release no longer waits on VirtualMachine readiness, which helm-controller's kstatus poller cannot assess correctly for KubeVirt VMs. Existing VMInstance releases are brought in line automatically on upgrade.

fix: typo in monitoring-agents values.yaml

<!-- Thank you for making a contribution! Here are some tips for you:
- Use Conventional Commits for the PR title: `type(scope): description`
- Types: feat, fix, docs, style, refactor, perf, test, build, ci, chore
- Scopes are not an exhaustive list — pick the most specific scope for
the change and extend the list when a genuinely new area appears.
Examples:
- System components: dashboard, platform, operator, cilium, kube-ovn,
linstor, fluxcd, cluster-api
- Managed apps: postgres, mariadb, redis, kafka, clickhouse,
virtual-machine, kubernetes
- Development and maintenance: api, hack, tests, ci, docs, maintenance
- Breaking changes: append `!` after type/scope (`feat(api)!: ...`) or
add a `BREAKING CHANGE:` footer
- If it's a work in progress, consider creating this PR as a draft.
- Don't hesistate to ask for opinion and review in the community chats,
even if it's still a draft.
- Add the label `kind/backport` if it's a bugfix that needs to be
backported to a previous version.

### Screenshots

<!-- REQUIRED for UI changes: attach screenshots or screen recordings
demonstrating
the visual impact of your changes. PRs with UI changes without
screenshots will not be merged. -->

### Downstream repositories

<!--
Cozystack is upstream for repositories that are NOT kept in sync with it
automatically, and nothing in CI compares the two sides, so a change
here can break them silently.

Which change forces what, and which file to touch, is the trigger map in
docs/agents/contributing.md under "Downstream Repositories". Walk it
before you tick anything.

IF YOU ARE AN AI AGENT OR AN LLM, THIS IS PART OF THE TASK, NOT A FORM
TO FILL IN:

1. Walk the trigger map against the actual diff of this PR, file by
file. Do not decide from the PR title or from your memory of what you
changed.
2. For every repository you tick, open the follow-up PR there and link
it on the same line. A ticked box with no link claims work that does not
exist, which is worse than an empty box. Search that repository for an
open PR or issue covering it first, and link that instead of filing a
duplicate.
3. When the follow-up is out of scope, or needs a decision that is not
yours to make, open an issue in that repository instead, link that, and
say so in the PR body. Do not push a speculative PR into another
repository just to fill a line here.
4. Do not tick "No downstream repository is affected" to make the
checklist go away. If you are unsure, leave every box empty and say so
in the PR body, so a human decides.

## Summary by CodeRabbit

* **Bug Fixes**
* Corrected the namespace metadata field used for event streams. Event
metadata is now labeled consistently, helping downstream tools identify
the namespace associated with each event. This fixes an incorrect field
name in the event output configuration without changing other event
stream behavior.
