docs(changelog): add sdk_only provider property entries

api/CHANGELOG.md

@@ -9,6 +9,7 @@ All notable changes to the **Prowler API** are documented in this file.
 - Provider type is validated against the SDK's available providers instead of a static enum, so the API accepts any installed provider (built-in or external); `Provider.provider` is stored as `varchar` and the native PostgreSQL enum is removed [(#11399)](https://github.com/prowler-cloud/prowler/pull/11399)
 - Compliance framework discovery is sourced from the SDK's available providers instead of a static enum, so an externally-registered provider's compliance frameworks are discoverable without API changes [(#11410)](https://github.com/prowler-cloud/prowler/pull/11410)
 - Compliance report availability (ThreatScore, ENS, NIS2, CSA) is derived from the provider's available compliance frameworks instead of hard-coded provider whitelists, so a provider that ships one of these frameworks gets the report without API changes [(#11412)](https://github.com/prowler-cloud/prowler/pull/11412)
+- Provider types exposed by the API (filter choices, serializer field, creation validation) are now limited to SDK providers that declare `sdk_only = False`, hiding CLI/SDK-only providers such as `llm`, `nhn`, `scaleway`, and `stackit` [(#11427)](https://github.com/prowler-cloud/prowler/pull/11427)

 - Support for external/custom providers, checks, and compliance frameworks without modifying core code [(#10700)](https://github.com/prowler-cloud/prowler/pull/10700)
 - Public `Provider.get_class()` method that resolves a provider class by name for both built-in and external (entry-point) providers [(#11398)](https://github.com/prowler-cloud/prowler/pull/11398)
+- `sdk_only` provider property (default `true`) and `Provider.get_app_providers()`, so a provider (built-in or external) stays CLI/SDK-only and hidden from the app unless it declares `sdk_only = False` [(#11427)](https://github.com/prowler-cloud/prowler/pull/11427)
