Release 4.3.0

[lennartvava]

4.3.0

Added

• API key authentication through ApiKeyConfiguration, using the apiKey and applicationId headers.
• LegacyConfiguration for clients that manage their own authentication, restoring the v3 configuration behavior.
• A shared ClientConfigurationInterface for endpoint, version, and timeout settings.
• A guide for upgrading from v3 to v4.3.

Changed

• The client now selects authentication based on the configuration interface.
• A token cache is required only for OIDC authentication.

Compatibility

Existing v4 OIDC consumers can upgrade without code changes. Configuration signatures, protected property types, and token-provider behavior remain unchanged.

Consumers upgrading from v3 should follow UPGRADE.md and require digipolisgent/api-client: ^4.3.
