- Add LLMRouter: grammar-constrained LFM call for intent classification after stage-0, before classifier cascade. Errors fall through gracefully. - Add IntentChat: conversational intent with no store side-effect, routed through LLM -> phraser chat endpoint. - Extract slots for Chat: no structured slots, full utterance is payload. - Extend stage-0 grammars to fire through Cyrillic wake-word spellings (Мэйвен/Мейвен/Майвен/etc.) produced by Russian STT model. - StripWakeToken helper strips leading wake in any script so time/date grammars still match when wake is present. - Add classifier examples for chat utterances (EN + RU). - Wire LLMRouter into Router.Config; optional, nil-safe.
