Changelog Entry

Description

Prevent duplicate loading of function modules by adding a caching helper function. Refactored existing code to use this cache, eliminating repetitive cache checks and improving performance by ensuring each function module is loaded only once per request.

Changed

Added get_function_module_from_cache() in plugin.py for caching loaded modules.
Refactored get_function_module() and related functions to utilize the cache.
Removed duplicate cache logic in filter, models, functions, chat, and router modules.
Reduced redundant module loads, improving performance and maintainability.
