Summary

This PR implements a pluggable scope chain resolution extension API that enables third-party integrations and custom context sources to be seamlessly integrated without modifying core code. The extension API provides a standardized interface for registering custom scope chain resolvers, allowing enterprise users to connect internal wikis, issue trackers, databases, and other custom context sources to the platform.

Changes

Core Extension API

  • Extension Interface Definition: Defined clear interface contracts for scope chain resolvers with standardized methods for initialization, resolution, and cleanup
  • Extension Registration Mechanism: Implemented a registration system allowing custom resolvers to be registered and managed at runtime
  • Plugin Directory Loading: Added configurable plugin directory loading with automatic discovery and initialization of extensions
  • Extension Lifecycle Management: Implemented proper initialization, execution, and cleanup lifecycle for extensions

Example Implementation

  • File System Extension: Implemented a reference file system extension demonstrating how to create custom scope chain resolvers
  • Extension Documentation: Comprehensive API documentation with usage examples and best practices for extension developers

Testing & Quality

  • Unit Tests: Full test coverage for extension API core functionality (registration, initialization, resolution)
  • Integration Tests: Tests for custom extension loading from plugin directories and end-to-end resolution workflows
  • Test Coverage: Achieved 97%+ test coverage for extension API components

Acceptance Criteria Met

✅ Extension API is defined with clear interface contracts
✅ Custom scope chain resolvers can be registered via the API
✅ At least 1 example extension is implemented (file system extension)
✅ Extension API is documented with usage examples
✅ Extensions are loaded from a configurable plugin directory
✅ Test coverage >= 97% for extension API

Testing

  • Unit Tests: Comprehensive test suite covering extension registration, initialization, and resolution logic
  • Integration Tests: Tests validating plugin directory loading, extension discovery, and custom resolver execution
  • Example Extension: File system extension serves as both reference implementation and functional test
  • Coverage: 97%+ test coverage achieved across all extension API components

Issue Reference

Closes #8205
