Wire Keel's Slack notifier to the existing bot token in Vault
(secret/viktor -> slack_bot_token). Posts to #general by default;
override via slack.channel in the Helm values if you want a dedicated
channel like #keel-notifications.
Notification level is "info" so we get every rollout event, not just
errors. Approval flow is OFF — opt-out-pure means all updates apply
unattended. If we later introduce approvals, add slack.approvalsChannel.
Resolves user request: 'keel should send notifications to slack everytime
it upgrades an app'.

The Helm repo at https://charts.keel.sh has versions 1.0.0–1.0.5,
1.1.0, 1.2.0. 1.0.6 is not published, so the Phase 0 apply failed
silently. Bump to 1.2.0 (app version 0.21.1, latest stable).
Foundation for opt-out-pure auto-update model per
docs/plans/2026-05-16-auto-upgrade-apps-{design,plan}.md.
- New stack `stacks/keel/` deploys Keel via Helm (charts.keel.sh, v1.0.6).
Polls registries hourly per design decision #8. Default schedule
overridable per-workload via keel.sh/pollSchedule annotation.
- New Kyverno ClusterPolicy `inject-keel-annotations` mutates Deployments,
StatefulSets, and DaemonSets in namespaces labeled `keel.sh/enrolled=true`
with keel.sh/policy=force + trigger=poll + pollSchedule=@every 1h.
- Phase 0 enrolls no namespaces. Phase 1 (next session) labels the
self-hosted set.
- Per-workload opt-out: label `keel.sh/policy: never` (used by rollback
runbook and chrome-service-style deliberate pins).
- Keel namespace excluded from the mutate — supervisor self-update has
too-bad a failure mode (decision #11).
- AGENTS.md: KYVERNO_LIFECYCLE_V2 marker convention added for the
ignore_changes block enrolled workloads need.
- .claude/CLAUDE.md: docker-images rule flagged as transitional.
