- Add llmphraser: LFM-based phraser implementing Phraser interface with PhraseChat, PhraseNudge, PhraseReactive, and PhraseReminder methods. - Add shared internal/llm/client: llama-server completion client used by both the phraser (talking back) and router (routing), sharing one model. - Add LLMReplier in mavend: replaces StubReplier for chat/nudge/reactive replies, falls back to stub on model errors. - Update Phraser interface: add PhraseChat method, update stub to match. - Wire LLM phaser into mavend voice init, plumb LLM config from JSON.

// Package llm is the shared llama-server completion client — one seam both the

// phraser (talking back) and the router (routing) call. It does NOT spawn the
|
|
// server; the daemon owns one llama-server (spawned by the phraser) and hands
|
|
// its base URL here, so a single resident model serves both callers.
