brian dc7abfd41a feat(rag): add EPUB file support for Knowledge Base uploads ... EPUBs are ZIP archives containing structured XHTML content with semantic chapter/section markup, making them well-suited for RAG text extraction and chunking. Changes: - Add 'epub' to determineFileType() in utils/fs.ts - Add processEPUBFile() method in rag_service.ts that: - Reads container.xml to locate the OPF manifest - Parses the OPF spine for correct reading order - Extracts text from each XHTML content document using cheerio - Falls back to all manifest items if no spine is found - Wire epub case into processAndEmbedFile() switch - Add jszip dependency for ZIP archive reading (cheerio already present) Closes #253-adjacent (epub is a common format for Project Gutenberg content and technical reference books)		2026-03-13 13:25:01 -04:00
