feat: 完成 F 群組 — 對話生成管線與 LLM Provider 抽象

- LLMProvider 介面（generate/stream）+ LLM_PROVIDER 切換（llm.module.ts useFactory， LLM_PROVIDER=mock|claude 環境變數決定注入哪個實作） - MockProvider：依性格原型 × 情緒狀態 × 親密度從模板庫選填回應，seeded PRNG 確保同 seed 可重現，支援＊動作描寫＊標記抽取（目前只有元氣原型模板，G 群組需補齊其餘五種原型） - ClaudeProvider 空殼：LLM_PROVIDER=claude 時啟動即輸出 ERR log，呼叫 generate/stream 時拋出例外 - OutputFilterService：全域＋角色禁則詞彙過濾（攔截並改寫） - FastChannelDetector：固定問候與危險輸入（含求助資源)走快速通道，跳過記憶檢索 - BehaviorReinforcementService：稱讚加權、糾正後修正版繼承舊權重以確保排序領先（實作時抓到並修正一個「降權後打平」的真實 bug） - ContextAssemblerService：組裝人設／情緒／關係／檢索記憶／對話歷史為統一上下文快照 - DialogueService/Controller：串起以上所有元件，作為 H-1 正式對話端點的基礎 - scripts/smoke/F.mjs：涵蓋可重現性、上下文快照完整性、雙速通道、行為強化、輸出過濾、以 child process 驗證 Provider 切換 npm run restart && npm run smoke -- F 皆通過（F-V），A/B/C/D/E 群組冒煙測試無回歸。
