"""
Hindsight Extensions System.

Extensions allow customizing and extending Hindsight behavior without modifying core code.
Extensions are loaded via environment variables pointing to implementation classes.

Example:
    HINDSIGHT_API_OPERATION_VALIDATOR_EXTENSION=mypackage.validators:MyValidator
    HINDSIGHT_API_OPERATION_VALIDATOR_MAX_RETRIES=3

    HINDSIGHT_API_HTTP_EXTENSION=mypackage.http:MyHttpExtension
    HINDSIGHT_API_HTTP_SOME_CONFIG=value

Extensions receive an ExtensionContext that provides a controlled API for interacting
with the system (e.g., running migrations for tenant schemas).
