Refactor and enhance LDAP plugin configuration and validation

- Updated `LdapPluginOptions` to enforce TLS and client certificate requirements.
- Added validation checks for TLS configuration in `LdapPluginOptionsTests`.
- Improved error handling in `DirectoryServicesLdapConnectionFactory` for StartTLS negotiation.
- Enhanced logging in `LdapCredentialStore` to include detailed audit properties for credential verification.
- Introduced `StubStructuredRetriever` and `StubVectorRetriever` for testing in `ToolsetServiceCollectionExtensionsTests`.
- Refactored `AdvisoryGuardrailPipelineTests` to improve test clarity and structure.
- Added `FileSystemAdvisoryTaskQueueTests` for testing queue functionality.
- Updated JSON test data for consistency with new requirements.
- Modified `AdvisoryPipelineOrchestratorTests` to reflect changes in metadata keys.

 > 2025-11-03: LDAP plugin RFC accepted; review notes in `docs/notes/2025-11-03-authority-plugin-ldap-review.md`. Follow-up implementation items PLG7.IMPL-001..005 added per review outcomes.
 > 2025-11-03: PLG7.IMPL-001 completed – created `StellaOps.Authority.Plugin.Ldap` + tests projects, implemented configuration normalization/validation (client certificate, trust store, insecure toggle) with coverage (`dotnet test src/Authority/StellaOps.Authority/StellaOps.Authority.Plugin.Ldap.Tests/StellaOps.Authority.Plugin.Ldap.Tests.csproj`), and refreshed `etc/authority.plugins/ldap.yaml`.
 > 2025-11-04: PLG7.IMPL-002 progress – StartTLS initialization now uses `StartTransportLayerSecurity(null)` and LDAP result-code handling normalized for `System.DirectoryServices.Protocols` 8.0 (invalid credentials + transient cases). Plugin tests rerun via `dotnet test src/Authority/StellaOps.Authority/StellaOps.Authority.Plugin.Ldap.Tests/StellaOps.Authority.Plugin.Ldap.Tests.csproj` (green).
+> 2025-11-04: PLG7.IMPL-002 progress – enforced TLS/client certificate validation, added structured audit properties and retry logging for credential lookups, warned on unsupported cipher lists, updated sample config, and reran `dotnet test src/Authority/StellaOps.Authority/StellaOps.Authority.Plugin.Ldap.Tests/StellaOps.Authority.Plugin.Ldap.Tests.csproj --no-restore`.
