Merged
Conversation
Extract <dc:subject> tags from EPUB OPF metadata and emit them as <atom:category> elements in acquisition feeds. Enables genre/subject filtering and display in OPDS clients that support categories. Changes: - Added Subjects []string to CatalogEntry - Extended extractEpubMetadata() to parse <dc:subject> with namespace fallback - Added Category struct to opds package (Term, Label, Scheme) - Extended Entry struct with Categories field - Added AddCategory() builder method - makeFeed() emits <atom:category> for each subject when ExtractMetadata is on
