ai_agents_ossa 1.0.0-alpha3

OSSA manifest management for Drupal — now bridging Modeler API and Context Control Center

New Submodules

• ai_agents_ossa_modeler
  
  ModelOwner bridge for the Modeler API. Exposes OSSA agent graphs (capabilities, successors, swimlanes) in the visual editor. Implements ModelOwnerInterface so agent manifests render as first-class Modeler entities.
• ai_agents_ossa_context
  
  CCC/ai_context bridge. Injects contextual pipelines (brand voice, regulatory constraints, domain rules) into agent execution at runtime.
• ai_agents_ossa_api_normalization
  
  Restored and fully implemented. Normalizes OSSA manifest data for Drupal's serialization layer, enabling clean REST/JSON:API exposure of agent configuration.

Bug Fixes

• Moved OssaAgentModelOwner to correct Plugin\ModelerApiModelOwner namespace — aligns with Modeler API plugin discovery.
• Fixed object type hint on optional ApiResponseEvent dependency — resolves fatal on sites without API normalization enabled.
• Fixed tool discovery in the ossa:demo Drush command.

Developer Experience

• Switched to drupal.org standard CI template (drupalci variables/workflows).
• Added Drupal 11 + PHP 8.3 CI target.
• PHPCS Drupal coding standards enforced — 102 violations resolved across 27 files.
• Bootstrapped local PHPCS tooling for contributors.
