Intelligent Translation Caching With Segment Deduplication

[EMNLP 2025 Demo] PDF scientific paper translation with preserved formats - 基于 AI 完整保留排版的 PDF 文档全文双语翻译，支持 Google/DeepL/Ollama/OpenAI 等服务，提供 CLI/GUI/MCP/Docker/Zotero

Unique: TranslationCache class in pdf2zh/cache.py uses SQLite with segment hashing for exact-match deduplication, tracking cost per service and enabling cache statistics — enables cost-aware translation routing and audit trails without external dependencies

vs others: More cost-effective than stateless translation by eliminating redundant API calls; more auditable than in-memory caches by persisting to SQLite with metadata
