• different llm/v2v extension support different tool set
• only registered modules should i appear, and its type should follow registry configs instead of addon name

Tasks

• create a module registry class for module management
• update cfg component to respect registry
• only compatible tools should be allowed to choose for different llm/v2v models

lgtm

    export type ModuleType = "stt" | "llm" | "v2v" | "tts";
    export type ToolModuleType = "tool";

May consider enum to limit variable range.
