Introduce ISynologyApiClient Facade

Features & Enhancements

• New ISynologyApiClient Facade (#79059f9): Introduced a unified API client to drastically streamline dependency injection and consumer usage. You no longer need to manually orchestrate ISynologyApiRequestBuilder and ISynologyApiService.
• Domain-Specific Clients (#79059f9): Added strongly-typed, domain-specific sub-clients accessible directly through the main facade:
  • ApiInfoClient
  • AuthClient
  • FileStationClient
  • FotoClient
  • FotoTeamClient
• Simplified Dependency Injection (#79059f9): Updated SdkConfigurationExtensions to automatically register the new ISynologyApiClient and its corresponding domain dependencies.

Deprecations

• Legacy Interfaces Marked Obsolete (#79059f9): The ISynologyApiRequestBuilder and ISynologyApiService interfaces have been marked with the [Obsolete] attribute. They are still functional in this release but are slated to become internal in a future major SDK release. Consumers are highly encouraged to migrate to ISynologyApiClient.

Chores & Maintenance

• Dependency Updates (#b3e241b): Updated internal NuGet packages to their latest stable versions.
• Testing Framework Update (#a07817c): Updated the TUnit test framework to the latest version.

Documentation Updates

• API Docs Refreshed (#79059f9): Updated the README.md, Docs/ConsumerSample.md, and all 14 individual API request .md files to accurately reflect the usage of the new ISynologyApiClient.
• Cleaned Up Outdated Documents (#f1d2498): Removed outdated implementation plans and obsolete API overview documentation from the repository.
