zeekayandHanzo Dev 446e343a3d cd: annotations are cd.hanzo.ai, API group is apps.hanzo.ai

Two corrections on top of the naming pass, both found by checking the live
cluster rather than the source.

The rename had silently changed the user-facing annotation key from
argocd.argoproj.io/sync-wave to cd.argoproj.io/sync-wave — 63 live
Applications carry the old key, so deploying that would have ignored every
sync-wave and broken fleet deploy ordering. The key is now cd.hanzo.ai/*,
and universe 575650286 moves the ApplicationSet template that stamps it, so
the controller regenerates all 63 consistently.

The API group in code said argoproj.io/v1alpha1 in 157 places while the
cluster has served apps.hanzo.ai/v1alpha1 since 2026-07-23 (the CRDs are
applications.apps.hanzo.ai). Code now matches what is actually served.

The legacy applications.argoproj.io/app-name label had ZERO live users, so it
went with the rest. foo.argoproj.io test fixtures became foo.example.com —
arbitrary test domains should not carry a vendor name.

go build ./... exit 0.

Architectural Overview

Components

API Server

The API server is a gRPC/REST server which exposes the API consumed by the Web UI, CLI, and CI/CD systems. It has the following responsibilities:

application management and status reporting
invoking of application operations (e.g. sync, rollback, user-defined actions)
repository and cluster credential management (stored as K8s secrets)
authentication and auth delegation to external identity providers
RBAC enforcement
listener/forwarder for Git webhook events

Repository Server

The repository server is an internal service which maintains a local cache of the Git repository holding the application manifests. It is responsible for generating and returning the Kubernetes manifests when provided the following inputs:

repository URL
revision (commit, tag, branch)
application path
template specific settings: parameters, helm values.yaml

Application Controller

The application controller is a Kubernetes controller which continuously monitors running applications and compares the current, live state against the desired target state (as specified in the repo). It detects OutOfSync application state and optionally takes corrective action. It is responsible for invoking any user-defined hooks for lifecycle events (PreSync, Sync, PostSync)
