refactor: 大幅清理 AIController 冗餘代碼並優化架構
主要優化： - 移除 AnalyzeLowValueWord 重複方法 (70+ 行) - 移除 IsHighValueWord 複雜判定邏輯 - 移除 GetHighValueWordAnalysis 假資料方法 - 完全重寫 QueryWord 方法，從 55 行簡化到 25 行 架構改善： - 統一使用 GeminiService.AnalyzeWordAsync 進行詞彙分析 - 移除高/低價值詞彙的複雜分支邏輯 - Controller 職責單純化，只負責 HTTP 請求處理 - 遵循 DRY 原則，避免重複代碼 代碼品質提升： - 總行數減少約 200 行 (-14%) - 移除 3 個重複方法 - 簡化錯誤處理邏輯 - 提升代碼可讀性和維護性 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
