Brings in upstream fixes from main while preserving the dnsplugins branch architecture (inline DNS providers removed in favor of external plugins resolved via IDomainValidatorFactory). Resolutions: - Kept deletion of inline Cloudflare/Google/Factory providers (moved to plugin projects on this branch). - Dropped provider-specific config fields/annotations re-added by main; those configs now belong to each DNS plugin. - Added main's new Enabled disable-switch: cached AcmeClientConfig in Initialize, early-return in Initialize, and FAILED enrollment when the connector is disabled. - Added main's DnsVerificationServer config (with annotation) for private DNS zones, and wired it into the DnsVerificationHelper constructor call in Enroll. - Kept dnsplugins' AcmeCaPlugin.csproj state (newer IAnyCAPlugin prerelease, Google package removed, other provider packages pending cleanup).

Ports the FlowLogger pattern from Keyfactor/barracuda-wafasaas-orchestrator and adapts it for an IAnyCAPlugin. The accumulated step breadcrumb is appended to EnrollmentResult.StatusMessage on both success and failure, so operators see a scannable per-step summary in the Command UI instead of just a single exception message. Changes: - FlowLogger.cs: ported verbatim from barracuda with namespace changed to Keyfactor.Extensions.CAPlugin.Acme. Added StepAsync<T> overload for async methods that return a value. - Enroll: wraps each stage (ValidateInput, FormatCsr, LoadConfig, CreateHttpClient, InitAcmeAccount, CreateAcmeClient, DecodeCsr, ExtractDomainsFromCsr, CreateOrder, ExtractOrderIdentifier, FinalizeOrder, DownloadCertificate, EncodeCertificateToPem) as a timed flow.Step. Success returns include flow.GetSummary(); failure paths include DescribeException(ex) + flow.GetSummary(). - ProcessAuthorizations: takes the flow and records per-domain work in three branches (StageDnsRecords / VerifyAndSubmit / CleanupDnsRecords), so the breadcrumb shows which specific domain failed when a challenge breaks. - DescribeException helper: unwraps AggregateException/TargetInvocation wrappers, surfaces HttpRequestException context, and truncates overlong messages so the summary stays readable. - Initialize: added ValidateConfigForEnrollment — fails fast (at save time, not first enroll) on missing DirectoryUrl/Email, non-absolute or non-http(s) DirectoryUrl, mismatched EAB key pair, or negative DnsPropagationDelaySeconds. Build: net6.0 / net8.0 / net10.0 — 0 errors, pre-existing warnings only. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Removed specific root/intermediate names (ISRG Root X1, R3) that go stale when Let's Encrypt rotates their chain. Users are now directed to the official Let's Encrypt certificates page to identify the currently active root and intermediate certificates.

Resolve the ACME challenge record name through any chain of CNAME delegations to its terminal target before staging validation. The resolved name now drives DNS provider plugin selection, record creation, propagation verification, and cleanup, so challenges delegated into a zone on a different provider are routed to the plugin that owns that zone. Non-delegated domains are unaffected.
Add multi-level CNAME delegation support for DNS-01 challenges
The framework's ResolveDomainValidator matches configured provider domain patterns (e.g. *.zone.com) against the certificate/zone name, not the _acme-challenge record name. Resolving on the raw resolved record name broke the non-delegated path because the _acme-challenge prefix fails the one-level wildcard match. Resolve the validator on the cert domain when no CNAME delegation exists, and on the resolved terminal target when it does, so both the direct and cross-zone delegated cases select the correct provider.
Fix validator resolution regression for non-delegated challenges

Pull request overview
This PR advances the ACME CA Gateway plugin toward a plugin-based DNS provider architecture by removing embedded DNS provider implementations, introducing CNAME-delegation support for DNS-01 challenges, and improving enrollment traceability/logging. It also updates target frameworks/dependencies and adds documentation around DNS provider plugin migration.
Changes:
- Externalizes DNS providers (removes embedded provider classes/factory + config fields) and introduces
IDomainValidatorFactory-based resolution during enrollment. - Adds CNAME delegation resolution for
_acme-challengeTXT placement and step-oriented flow logging for enrollment troubleshooting. - Updates TFMs/dependencies (drops
net6.0, bumps Keyfactor/AWS/Azure packages) and refreshes docs/changelog/workflow.

Add a CNAME Delegation section to docsource/configuration.md describing why challenge names are delegated to an isolated validation zone, how the CnameResolver follows a multi-level CNAME chain to its terminus, how the DNS provider plugin is selected against the resolved target (enabling cross-provider delegation), the loop/depth safety guards, and private-zone resolution via DnsVerificationServer. Update the enrollment flow summary to include the CNAME resolution step.
Cname delegation dnsplugins
DNS providers are now standalone, pluggable plugins deployed alongside the AnyCA Gateway rather than built into this ACME plugin. Remove the hardcoded "supported DNS providers" lists, per-provider credential/config tables, RFC 2136 setup, and the obsolete IDnsProvider/DnsProviderFactory "adding new providers" guidance. Point instead to the Keyfactor -dnsplugin repositories query as the authoritative source, and document that providers are configured via the Gateway's Domain Validation config and resolved per domain (including CNAME-delegated targets).
Cname delegation dnsplugins
DNS providers are now separate plugins, so the ACME plugin no longer needs their SDKs or per-provider config fields. Drop the AWS, Azure, ARSoft (RFC2136), and Nager.PublicSuffix package references (all unused in code) and remove the DnsProvider selector plus every per-provider config entry from the integration manifest. Keep the ACME-level fields, AccountStoragePath (still used for account storage), and DnsVerificationServer (used for propagation checks and CNAME resolution). DnsClient is retained for CNAME delegation and TXT propagation.
