"""
Atomizer Plugin System

Enables extensibility through hooks at various stages of the optimization lifecycle.

Hook Points:
- pre_mesh: Before meshing operations
- post_mesh: After meshing, before solve
- pre_solve: Before solver execution
- post_solve: After solve, before result extraction
- post_extraction: After result extraction, before objective calculation
- custom_objectives: Custom objective/constraint functions

Usage:
    from optimization_engine.plugins import HookManager

    hook_manager = HookManager()
    hook_manager.register_hook('pre_solve', my_custom_function)
    hook_manager.execute_hooks('pre_solve', context={'trial_number': 5})
