+/// <summary>
+/// Configures CoreDNS on the cluster by patching the "coredns" and "coredns-custom"
+/// ConfigMaps in kube-system. Unlike most other components that deploy via Helm,
+/// CoreDNS is already running on every Kubernetes cluster — we just customize it.
+///
+/// This installer supports three types of customization:
+///
+/// 1. **Stub zones** — Forward queries for specific domains to internal DNS servers.
+///    Format: "domain=ip1,ip2;domain2=ip3" → generates server blocks with forward directives.
+///    Example: "corp.internal=10.0.0.53,10.0.0.54;db.internal=10.1.0.53"
+///
+/// 2. **Custom Corefile entries** — Additional plugin directives injected into the
+///    main server block (e.g., rewrite rules, logging, template records).
+///    Format: Raw Corefile plugin text (newline-separated).
+///
+/// 3. **Custom DNS records** — Static A records stored in the "coredns-custom" ConfigMap
+///    and imported via the hosts plugin.
+///    Format: "hostname=ip;hostname2=ip2" → generates hosts-format entries.
+///
+/// Configuration keys:
+/// - "stubZones": Semicolon-separated zone definitions (zone=ip1,ip2)
+/// - "customCorefileEntries": Raw plugin text to inject into the main server block
+/// - "customRecords": Semicolon-separated static A records (hostname=ip)
+///
+/// After patching the ConfigMap, CoreDNS pods automatically reload the configuration
+/// (CoreDNS watches ConfigMap changes and hot-reloads within ~30s).

+/// <summary>
+/// Provisions, imports, or adopts domain-scoped Certificate Authorities.
+/// Unlike the platform internal-ca (general purpose), domain CAs are restricted
+/// to signing certificates only for specific DNS domains.
+///
+/// Three modes of operation:
+///
+/// **1. Provision a new domain CA (self-signed)**
+/// Creates a new self-signed root CA scoped to specific domains.
+/// Use case: internal private domains like *.internal.corp.com
+/// Parameters: caName, domains, caOrganization, caDurationDays
+///
+/// **2. Import an external CA (cert + key provided)**
+/// Imports a purchased CA certificate and private key as a K8s TLS Secret,
+/// then creates a CA ClusterIssuer referencing it. cert-manager can now sign
+/// certificates for those domains using the imported CA.
+/// Use case: DigiCert/Sectigo intermediate CA for *.example.com
+/// Parameters: caName, importExternal=true, tlsCert, tlsKey, domains
+///
+/// **3. Trust-only import (cert only, no key)**
+/// Imports just the CA certificate into the trust bundle. No ClusterIssuer
+/// is created because we can't sign certs without the private key.
+/// Use case: Partner API CA, corporate PKI root that services need to trust
+/// Parameters: caName, importExternal=true, tlsCert (no tlsKey), domains (optional)
+///
+/// All modes add the CA root certificate to the trust-manager Bundle so
+/// workloads automatically trust certificates signed by these CAs.
+///
+/// Configuration keys:
+/// - "caName": Identifier for this domain CA (used as ClusterIssuer name)
+/// - "domains": Comma-separated list of domains this CA covers (e.g., "*.internal.corp.com,*.svc.local")
+/// - "importExternal": "true" to import an existing cert rather than self-signing
+/// - "tlsCert": Base64-encoded PEM certificate (required for import)
+/// - "tlsKey": Base64-encoded PEM private key (optional — if absent, trust-only)
+/// - "caOrganization": Organization field for self-signed CAs (default: "EntKube Domain CA")
+/// - "caDurationDays": Validity in days for self-signed CAs (default: "1825")
+/// - "bundleName": Trust bundle to add the CA to (default: "platform-trust-bundle")

+/// **Istio mode** (provider=istio):

+/// - External ingress gateway (optional) in external-ingress namespace
+/// - Gateway API Gateway resources with HTTPS listeners

+/// Configuration keys:
+/// - "provider": "traefik" or "istio" (required)

+/// <summary>
+/// Provisions or adopts an internal Certificate Authority using cert-manager.
+/// The internal CA is a self-signed root that signs all platform-internal TLS
+/// certificates (service-to-service mTLS, webhook certs, etc.). Its root
+/// certificate is injected into the trust-manager Bundle so every workload
+/// trusts it automatically.
+///
+/// The provisioning chain:
+/// 1. Create a self-signed ClusterIssuer (bootstrap — signs the CA cert itself)
+/// 2. Create a Certificate resource for the root CA (signed by the self-signed issuer)
+/// 3. Create a CA ClusterIssuer that references the root CA secret
+/// 4. Add the root CA certificate to the trust-manager Bundle
+///
+/// Adoption path:
+/// 1. Discover an existing CA ClusterIssuer
+/// 2. Read its root certificate from the referenced Secret
+/// 3. Add it to the trust bundle (if not already there)
+///
+/// Configuration keys:
+/// - "caName": Name for the CA Certificate and ClusterIssuer (default: "platform-internal-ca")
+/// - "bundleName": Trust bundle to add the CA cert to (default: "platform-trust-bundle")
+/// - "caOrganization": Organization field in the CA cert (default: "EntKube Platform")
+/// - "caDurationDays": Validity period in days (default: "3650")
+/// - "adoptExisting": "true" to adopt an existing CA instead of creating a new one
+/// - "existingIssuerName": Name of existing CA ClusterIssuer to adopt

+/// <summary>
+/// Installs trust-manager via Helm and creates a platform-wide Bundle CR that
+/// distributes CA certificates to all namespaces. Trust-manager is the mechanism
+/// by which internal CA certs (from cert-manager) and external CA certs (added
+/// by admins) become available as trusted roots in every workload.
+///
+/// What gets deployed:
+/// 1. trust-manager controller in the cert-manager namespace
+/// 2. A Bundle CR that aggregates CAs from multiple sources
+/// 3. ConfigMap targets in each namespace with the bundle data
+///
+/// Configuration keys (install):
+/// - "bundleName": Name of the Bundle CR (default: "platform-trust-bundle")
+/// - "targetNamespaces": Namespace selector — "*" for all, or comma-separated list
+/// - "includeDefaultCAs": Whether to include the system default CA bundle (default: true)
+/// - "targetKey": Key name in the target ConfigMap/Secret (default: "ca-certificates.crt")
+///
+/// Configuration keys (configure):
+/// - "addCertificate": "true" to add a certificate
+/// - "certificateName": Identifier for the certificate (used as ConfigMap name)
+/// - "certificateData": Base64-encoded PEM certificate data
+/// - "removeCertificate": Name of certificate to remove from bundle
+/// - "bundleName": Which bundle to modify (default: "platform-trust-bundle")
