Describe your changes

  • Added a new component registry system for CCv2. This implementation includes:
    • BidiComponentDefinition class to store component metadata, content, and file paths
    • BidiComponentRegistry class for thread-safe registration and retrieval of components
  • The registry provides a centralized store for component definitions with proper path resolution against caller files and thread-safe operations.
  • No user-facing API is exposed yet. These are internal building blocks to wire into registration/execution in follow-up work.

Testing Plan

  • Unit Tests (Python): Added comprehensive test suite in test_component_registry.py covering:
    • Path classification and resolution
    • Asset URL overrides and defaults
    • Subpath preservation in URLs
    • Component registration with asset overrides
    • Component update and name enforcement
